UniProt Protein Function: | Spinlw1: Serine protease inhibitor that plays an essential role in male reproduction and fertility. Modulates the hydrolysis of SEMG1 by KLK3/PSA (a serine protease), provides antimicrobial protection for spermatozoa in the ejaculate coagulum, and binds SEMG1 thereby inhibiting sperm motility. 3 isoforms of the human protein are produced by alternative splicing. |
UniProt Protein Details: | Protein type:Inhibitor; Secreted; Secreted, signal peptide; Cancer Testis Antigen (CTA) Chromosomal Location of Human Ortholog: 20q13.12 Cellular Component: cell surface; extracellular region Molecular Function:serine-type endopeptidase inhibitor activity; protein binding Biological Process: defense response to bacterium; negative regulation of peptidase activity |
NCBI Summary: | This gene encodes an epididymal protease inhibitor, which contains both kunitz-type and WAP-type four-disulfide core (WFDC) protease inhibitor consensus sequences. Most WFDC genes are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. This gene is a member of the WFDC gene family and belongs to the telomeric cluster. The protein can inhibit human sperm motility and exhibits antimicrobial activity against E. coli, and polymorphisms in this gene are associated with male infertility. Read-through transcription also exists between this gene and the downstream WFDC6 (WAP four-disulfide core domain 6) gene. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2014] |
