Summary: This gene encodes a member of the peptidase family. The protein forms a homodimer that hydrolyzes dipeptides or tripeptides with C-terminal proline or hydroxyproline residues. The enzyme serves an important role in the recycling of proline, and may be rate limiting for the production of collagen. Mutations in this gene result in prolidase deficiency, which is characterized by the excretion of large amount of di- and tri-peptides containing proline. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]
Expression: Broad expression in kidney (RPKM 221.6), small intestine (RPKM 95.0) and 19 other tissues See more

We found that prolidase levels are significantly higher in PCOS (polycystic ovary syndrome), but that rs267606943 is not associated with prolidase levels. Moreover, no allelic frequency and genotype difference was observed between the PCOS and the control group, providing an insight that rs267606943 is also not associated with the risk of PCOS

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
