Description

 Semenogelin I (HGNC Symbol)

Entrez gene summary

 The protein encoded by this gene is the predominant protein in semen. The encoded secreted protein is involved in the formation of a gel matrix that encases ejaculated spermatozoa. The prostate-specific antigen (PSA) protease processes this protein into smaller peptides, with each possibly having a separate function. The proteolysis process breaks down the gel matrix and allows the spermatozoa to move more freely. The antimicrobial peptide SgI-29 is an antimicrobial peptide with antibacterial activity.
