Definitions
- This invention relates to novel peptides and pharmaceutical formulations containing them; the pep- tides are useful as inhibitors of keratinocytes.
- leukocytes are pedtidergic cells.
- Neutrophil granules contain large amounts of basic, cystine-rich peptides of 29 to 34 amino acids, that have been variously called de- fensins (1), coricostatins (2), myeloid-related sequences (3), and cryptidins (4).
- de- fensins (1) basic, cystine-rich peptides of 29 to 34 amino acids
- coricostatins (2) coricostatins (2)
- myeloid-related sequences (3) myeloid-related sequences
- cryptidins cryptidins
- corti- costatins have potential regulatory functions, includ- " ing the ability to inhibit the action of the hormone adrenocorticotropin on glucocorticoid secretion (2,6,7) and to stimulate nifedipine-sensitive L-type Ca ⁇ + channels in villus enterocytes (8). It has also been reported that a human defensin is a monocyte chemotactic agent (9). Other granulocyte-associated peptides have also been shown to have regulatory activities. For example, hemoregulatory peptide 1 is a granulocyte-associated thiol containing pentapep- tide, with potent inhibitory actions on myelopoieses (10).
- Granulocyte enriched extracts contain several cystine-rich components at levels approximately three orders of magnitude lower than the defensin/corticostatins. From their compositional analysis and chromatographic behaviour these peptides appear unrelated to any known hormone, including the definsin/corticostatins.
- Gran- ulocyte-derived peptides have potential both as immunoregulatory molecules, and in host resistance.
- Granulins are novel candidate growth factors recently discovered in human and rat inflammatory leukocytes (22). Two rat granulin homologs, epithelin 1 and 2, occur in the kidney (23). Epithelin 1, which is probably identical to rat leukocyte granulin (22,23) exhibits activities similar to epidermal growth factor on epithelian cells .in vitro (23) .
- the invention relates to a family of novel leukocyte-associated peptides that are cystine-rich.
- the peptides are approximately 6 Kda and may be cytokines.

- S-pyridylethylated peptides were digested using trypsin (TPCK-treated, Sigma) chymotrypsin (Sigma), and S. aureus V8 protease (Sigma), at enzyme to substrate ratios of approximately 1 to 50 by weight. Digestions were performed at 37°C in 100 ⁇ l
- proteolytic fragments were then fractionated by rp-HPLC on a C-ig ⁇ Bondapak column using a gradient of
- HPLC profile of a typical extract of human inflammatory cells is shown in Figure 1.
- HP-1 and HP-4 several low abundance components are present.
- three low abundance components that had unusually high levels of cystine were identified... These are labelled A, B and C/D, and were present in both whole cell extracts (FIG. IB) and crude granule preparations (FIG. IA) .
- Each of these extracts was then further purified using size-exclusion HPLC, revealing that the component C/D
- SUBSTITUTE SHEET contained two peptides, one of which, D, eluted as a larger molecule than the other three. Each peptide was further purified on rp-HPLC. Their amino acid compositions are given in Table 1. The purified peptides were S-pyridylethylated, and amino terminal sequence analyses were performed, revealing that the four peptides were distinct but related molecules with no homology to any known protein. Because these peptides were associated with the granule fraction, we call them granulins A, B, C and D. Granulin D was run on reducing and non-reducing SDS-PAGE, and ran as a smaller molecule after reduction, indicating that it is probably a dimer.
- Granulin A is the most abundant of the human granulins, and was subject to a more detailed analysis. S-pyridylethylated peptide was digested with trypsin, chy otrypsin or S. aureus V8 protease. The fragments were isolated by HPLC, one fifth aliquots analysed by amino acid analysis, and appropriate fragments were then submitted to gas phase Edman microsequencing. Final recovery of the digestion products was between 150 and 300 picomoles. The overlap of the granulin A fragments is described in the legend to Table 2 together, with similar data for the rat granulin. The two sequences are highly
- SUBSTITUTE SHEET conserved, as would be expected for regulatory molecules. Inflammatory exudates and bone marrow preparations are mixtures of cells, the exudates containing typically 70 to 95% granulocytes. When leukocytes from the blood of healthy donors was fractionated by density gradient centrifugation, granulins could be detected in the granulocyte pellet, but not in the interface where the mononuclear cells partition (data not shown). The isolation and characterization of a novel family of leukocyte associated cystine-rich peptides, which are called granulins has been described.
- SUBSTITUTESHEET present it is not certain if both peptides are the product of the same, or different genes. It is also too early to determine whether the epithelins are intrinsic to renal cells, or if they are derived from blood borne cells trapped in the kidney. It is clear, however, that the two peptides from the kidney are members of a larger family, the granulins, and that a major source of the granulins, and probably also the epithelins, is from circulating leukocytes. Rat granulin was isolated from bone marrow, indicating that granulins are of myeloid origin. Whether granulins are also synthesized in circulating leukocytes remains to be determined.
- Granulins were extracted from granulocyte rich preparations, and are recoverable from the granulocyte pellet after Ficoll- Hypaque density gradient centrifugation. This suggests that their cellular origin may be the neutrophil, however, it is possible that other granulocytes such as eosinophils, or contaminating monocytes, contribute to the granulin content of these extracts. Extracts of human platelets contained no detectable granulins (data not shown). It is possible that each granulin belongs to a distinct cell type, or that sub-classes of the same cell-type contain different granulins. These are issues best answered using immunolocalization procedures. The granulins co-purify in a crude granule extract.
- Granulocytes have several different granule subclasses, including a true secretory compartment (21) that can be activated independently of phagocytosis.
- a true secretory compartment (21) that can be activated independently of phagocytosis.
- suitable immunoassay techniques will permit the unambiguous location .of the granulins to a cell type, and a subcellular compartment.
- the granulins are a novel family of cystine- rich immunoinflammatory peptides. Their presence in circulating leukocytes and inflammatory exudates, and
- granulins a novel class of leukocyte peptides with possible cytokine-like activities which are called granulins. They are cystine-rich with molecular weights of approximately 6Kda, except for granulin D, which appears to be a dimer.
- the sequence of one member of this family, a 56 residue peptide, granulin A, and amino-terminal sequences for three other granulins from human peripheral leukocytes are described.
- a fifth related peptide was isolated and partially sequenced from rat bone marrow, suggesting that at least some of the granulin in peripheral leukocytes is preformed in the marrow.
- Rat granulin, and human granulin A are closely related, showing that the granulin structures are highly conserved between species. It has now been found that the precursor for the human granulins is a 593 residue glycoprotein, containing seven repeats of the 12-cys mecanic granulin domain. Gene expression is seen in the kidney, leukemic cell lines and fibroblasts, and very strongly in transformed epithelial cell lines, which both express the gene, and respond to the mature polypeptide.
- Human leukocytes contain four granulin homologs, designated A, B, C and D. Their cellular distribution, and whether they are products of one or several genes under co-ordinate or independent control was unknown. To address these, and related issues, two oligonucleotide primers for PCR were synthesized corresponding to the amino terminal and mid-portion regions of granulin A (grnA). GrnA was chosen because it is the most abundant granulin in human leukocyte
- the sequence (Fig. 4C) predicts a protein of 593 residues, with a probable signal peptide (24) extending to residue 17. It contains the 56 residue grnA sequence, as expected, and also six other 12- cysteine granulin-like domains, including B, C and D, hitherto known only from N-terminal sequences.
- the precursor contains two novel Cys-12 domains, E and F, and a degenerate granulin domain, G, with 10 cysteines.
- the positions of the cysteines are highly conserved (Fig. 5) as are certain other residues such as ASP39, His42 and Pr ⁇ 4g.
- An eighth domain at the N- terminus, (paragranulin, Fig. 5) contains only 6 cysteines corresponding to the amino-terminal half of a granulin domain.
- the inter-domain sequences show little homology, except for a pro-ala dipeptide, found midway between each domain except F and G.
- Mono- or dibasic sequences which are frequent sites of proteolysis in peptide processing (25), flank granulin domains C, D and E, but not A or B, both of which have been isolated as excised peptides. Thus nothing can be
- EGF and granulin/epithelins have similar actions on epithelial cells (23), but probably different receptors (23). Whether the similarities are significant, or merely coincidental, is unclear. Unlike the EGF-precursor, pro-granulin has no transmembrane segment or cytoplasmic domain (28,29) implying different post-translational pathways for the two proteins. Multiple sequential repeats of cysteine-rich domains is a recurrent structural motif among regulatory proteins (28,29,30,31), wherein typically, one exon delineates one cysteine-rich domain (30,32,33). In contrast, the PCR amplified fragment of grnA is bisected by an intron (Fig. 4A), and preliminary results show that introns bisect domains G, F, B, C and D.
- cysteines align with an approximately mirror-image symmetry around the bisecting intron. Genomically, therefore, pro- granulin bears little resemblance to the EGF- precursor.
- Proerythroid leukemic cells express granulin mRNA (Fig. 7A) , but seem unlikely to be involved in regulating epithelial proliferation. Similarly, the
- SUBSTITUTE SHEET strong expression of granulin in RNA in kidney, but not other tissues, may imply functions unrelated to epithelial cell mitogenesis.
- granulins may have multiple biological activities; indeed distinct activities may be associated with different domains, as already proposed for epithelins 1 and 2 (23) .
- the availability of cloned granulins permit these questions to be addressed.
- FIG. 4. shows the sequence of the probe used to screen a human bone marrow cDNA library in gtll (Clontech, Palo Alto, CA. ) .
- the probe was generated by PCR of human DNA, with forward and reverse primers (underlined) based on the amino acid sequence of granulin A.
- the nucleotides in lower case represent an intron in the coding region of granulin A.
- Fig. 4B shows the sequencing strategy.
- the nucleotide sequence is a composite of three sequences HBM12, HBM3 and HNM4.
- Fig. 4C shows the complete nucleotide sequence and deduced polypeptide sequence of granulin. The nucleotides are numbered from the initiator codon (ATG), and the amino acids from the probable signal peptide cleavage site. Underlined sequences correspond to sequences previously determined by gas-phase microsequencing of purified granulins.

- the boxed nucleotides corresponds to a polyadenylation signal.
- Clone HBM12 starts at nucleotide 6.

- the amplified product was subcloned into the plasmid vector Bluescript KSII+ and its identity confirmed by double stranded dideoxynucleotide sequencing with Sequenase (USB). This fragment was labeled with 32 P by nick-translation (Boehringer Mannheim) and used to probe a human bone marrow cDNA library in ⁇ gtll (Cl ⁇ ntech, Palo Alto, CA. ) consisting of 1.51 X10 6 independent clones. Duplicate nitrocellulose filters (Schleicher and Schuell) were prehybridized in 5X SSC, 5X Denhardt's reagent, 0.2% SDS at 37°C for 5 hours.
- Hybridization was in 5X SSC, 2.5X Denhardt's reagent, 0.2% SDS, 50% formamide, 10% polyethylene glycol with 1x10? cpm probe at 37°C for 12 hours. Filters were washed twice for 45 minutes in 2X SSC, 0.1% SDS at 58°C and exposed at -70°C with Kodak X-Omat film with an intensifying screen. 16 positives were obtain from 3x10 ⁇ clones screened. The cDNA insert from clone HMB12 was digested with Kpnl and Sad, and the resulting cDNA fragments subcloned into Bluescript KSII+.
- Nucleotide sequence was determined by double stranded dideoxy sequencing using Sequenase (USB).
- the sequence of HBM12 lacked an initiator methionine.
- the remaining positive clones were analysed using PCR with ⁇ gtll sequence specific primers in combination with a primer, cll2rp, corresponding to nucleotides 45 to 61 of clone HBM12.
- Fig.5. Comparison of the granulin-like domains. Residues occuring three or more times are boxed, and dashes have been introduced to align the cysteines.
