Stiles and coworkers originally identified a gene they termed JE that is transcriptionally activated in mouse fibroblasts early after treatment with platelet derived growth factor or serum. This gene, now named Sigi'e, can encode a 148-amino acid secreted, basic polypeptide that belongs to the small inducible gene (SIG) family whose members include, for example, platelet factor 4. melanoma growth stimulatory activity (Mgsa). and interferon inducible protein 10. SIG family members share a conserved array of cysteine and proline residues and a similar predicted secondary.
