Sperm antigen HE2 (IPR007988)

Short name: Sperm_Ag_HE2

Family relationships



This family consists of several variants of the human and chimpanzee (Pan troglodytes) sperm antigen proteins (HE2 and EP2 respectively). The EP2 gene codes for a family of androgen-dependent, epididymis-specific secretory proteins.The EP2 gene uses alternative promoters and differential splicing to produce a family of variant messages. The translated putative protein variants differ significantly from each other. Some of these putative proteins have similarity to beta-defensins, a family of antimicrobial peptides [PMID: 10819450].
