The human neutrophil-derived cationic peptide HP-4 exhibits corticostatic activity on adrenal cells and is an L-type calcium channel agonist at nanomolar concentrations. Complementary DNA clones encoding the HP-4 precursor have been isolated from a human bone marrow cDNA library by screening with oligonucleotide probes. The nucleotide sequence shares about 72% identity with the cDNA encoding defensin HP-1, but differs from it, and from other genes of this family characterized to date, by an extra 83-base segment. This extra segment is not adjacent to an intron and is apparently the result of a recent duplication within the coding region corresponding to most of the mature HP-4 peptide. The predicted amino acid sequence shows the HP-4 precursor structure to be typical of this family of molecules. By analysis of DNA from a pannel of hamster/human hybrid cell lines, the HP-4 gene was found to be on chromosome 8, as is the gene for human peptide HP-1. Comparison with the few sequences of other corticostatin/defensin genes available does not indicate distinct lineages of corticostatic and noncorticostatic peptides, since HP-1 and HP-4 cDNA sequences share more identity with each other than either shares with cDNAs encoding rabbit MCP-1 or MCP-2, or guinea pig GNCP-1.

The gene encoding the human corticostatin HP-4 precursor contains a recent 86-base duplication and is located on chromosome 8.
