Semenogelin (IPR008836)

Short name: Semenogelin

Overlapping homologous superfamilies

None.

Family relationships

None.

Description

This family consists of several mammalian secreted seminal proteins including semenogelin I and II. Freshly ejaculated Homo sapiens semen has the appearance of a loose gel in which the predominant structural protein components are the seminal vesicle secreted semenogelins (Sg) [PMID: 1584792]. This family also includes seminal vesicle secretory protein 3A from mouse, which has been shown to be involved in the coagulation of semen resulting in the formation of the copulatory plug [PMID: 11723121].
