Precursor
secreted as an inactive pro-enzyme, which is able to autoactivate to gain enzymatic activity
involved in pathogenesis and/or progression of certain cancer types
possesses trypsin-like activity, cleaving peptide bonds after both arginine and lysine
may participate in enzymatic cascades involving other kallikreins
may indirectly regulate the bioavailability and activity of several growth factors through processing of their CCN binding partners
involvement of KLK12 in different homeostatic and disease pathways through modulation of growth factor availability and/or activity
play a critical role in controlling normal angiogenesis
KLK12-mediated proteolysis of CYR61 and WISP3 can reduce or abolish the binding of VEGFA, BMP2, and TGFB1
KLK12-mediated hydrolysis of CCNs may be involved in the modulation of the bioavailability and/or activity of several growth factors including VEGFA, BMP2, TGFB1, and FGF2
may play an important role in angiogenesis modulating proangiogenic factor bioavailability and activating the kinin receptor B2 pathway
proangiogenic activity of KLK12 in lung endothelial cells was not related to a kinin release
KLK5, KLK12 are involved in the cleavage activation of human-adapted influenza virus subtypes
KLK12 proangiogenic effect is mediated through several molecular mechanisms
plays likely a tumor-supporting role in Triple-negative breast cancer (TNBC)

might be responsible for the shedding of CYR61 from the cell surface
can target all six members of the CCN family at different proteolytic sites (WISP1, WISP2, WISP3, CYR61, CTGF, NOV)
interacting with CYR61 and WISP3 (fragmentation of CYR61 and WISP3 by KLK12 on cells of the tumor microenvironment, including neoplastic and endothelial cells)
angiogenesis is stimulated by KLK12 acting via a PDGFB-dependent paracrine pathway
efficiently cleaved the extracellular matrix proteins fibronectin and tenascin, both of which are involved in the regulation of endothelial cell adhesion and migration
