Kallikrein-14

Gene

KLK14

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Serine-type endopeptidase with a dual trypsin-like and chymotrypsin-like substrate specificity. May activate/inactivate the proteinase-activated receptors F2R, F2RL1 and F2RL3 and other kallikreins including KLK1, KLK3, KLK5 and KLK11. May function in seminal clot liquefaction through direct cleavage of the semenogelin SEMG1 and SEMG2 and activation of KLK3. May function through desmoglein DSG1 cleavage in epidermal desquamation a process by which the most superficial corneocytes are shed from the skin surface. May be involved in several aspects of tumor progression including growth, invasion and angiogenesis.6 Publications

Enzyme regulationi

Inhibited by SERPINA1, SERPINC1, SERPINE1, SERPINF2, aprotinin, soybean, trypsin inhibitor and leupeptin. Inhibited by serine protease inhibitor SPINK5. Has an autoproteolytic activity which may have a regulatory effect. Activated by citrate and inhibited by zinc and to a lower extent by manganese.3 Publications

Kineticsi

Has a higher catalytic efficiency for the trypsin-like enzyme substrates S-2288, S-2222 and S-2302 compared to S-2586 a chymotrypsin-like enzyme substrate. Has a lower catalytic activity compared to trypsin towards S-2288, S-2222 and S-2302. Cleaves preferentially after Arg residues.

    Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
    100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
    90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
    50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
