Protein

Kallikrein 1-related peptidase b27

Gene

Klk1b27

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Serine protease with chymotrypsin-like cleavage specificity. Shows activity towards casein, gelatin, IGFBP3 and fibronectin but not towards laminin or collagens I and IV. Does not hydrolyze kininogin to release Lys-bradykinin.

Enzyme regulationi

Strongly inhibited by protease inhibitors diisopropyl fluorophosphate, phenylmethanesulfonyl fluoride and SBTI.1 Publication

Similar proteinsi

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 one 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.
