Summaries for KLK2 Gene

Entrez Gene Summary for KLK2 Gene

  • This gene encodes a member of the grandular kallikrein protein family. Kallikreins are a subgroup of serine proteases that are clustered on chromosome 19. Members of this family are involved in a diverse array of biological functions. The protein encoded by this gene is a highly active trypsin-like serine protease that selectively cleaves at arginine residues. This protein is primarily expressed in prostatic tissue and is responsible for cleaving pro-prostate-specific antigen into its enzymatically active form. This gene is highly expressed in prostate tumor cells and may be a prognostic maker for prostate cancer risk. Alternate splicing results in both coding and non-coding transcript variants.

GeneCards Summary for KLK2 Gene

KLK2 (Kallikrein Related Peptidase 2) is a Protein Coding gene. Diseases associated with KLK2 include prostate cancer and male reproductive organ cancer. Among its related pathways are Endocrine and other factor-regulated calcium reabsorption and Agents Acting on the Renin-Angiotensin System Pathway, Pharmacodynamics. GO annotations related to this gene include serine-type endopeptidase activity. An important paralog of this gene is KLK12.
