Summaries for KLK11 Gene

Entrez Gene Summary for KLK11 Gene

  • Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers. This gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. Alternate splicing and the use of alternate promoters results in multiple transcript variants encoding distinct isoforms which are differentially expressed. [provided by RefSeq, Dec 2016]

GeneCards Summary for KLK11 Gene

KLK11 (Kallikrein Related Peptidase 11) is a Protein Coding gene. Among its related pathways are MSP-RON Signaling and Collagen chain trimerization. Gene Ontology (GO) annotations related to this gene include serine-type endopeptidase activity and serine-type peptidase activity. An important paralog of this gene is ENSG00000269741.

UniProtKB/Swiss-Prot for KLK11 Gene

  • Possible multifunctional protease. Efficiently cleaves bz-Phe-Arg-4-methylcoumaryl-7-amide, a kallikrein substrate, and weakly cleaves other substrates for kallikrein and trypsin. Cleaves synthetic peptides after arginine but not lysine residues.
