Family

Sperm antigen HE2 (IPR007988)

Short name: Sperm_Ag_HE2

Overlapping homologous superfamilies

None.

Family relationships

None.

Description

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].
