Function

[KLK6_HUMAN] Serine protease which exhibits a preference for Arg over Lys in the substrate P1 position and for Ser or Pro in the P2 position. Shows activity against amyloid precursor protein, myelin basic protein, gelatin, casein and extracellular matrix proteins such as fibronectin, laminin, vitronectin and collagen. Degrades alpha-synuclein and prevents its polymerization, indicating that it may be involved in the pathogenesis of Parkinson disease and other synucleinopathies. May be involved in regulation of axon outgrowth following spinal cord injury. Tumor cells treated with a neutralizing KLK6 antibody migrate less than control cells, suggesting a role in invasion and metastasis.^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

A series of hK6 inhibitors with a para-amidobenzylamine P1 group and a 2-hydroxybenzamide scaffold linker was discovered through virtual screening. The X-ray structure of hK6 complexed with compound 9b was determined to a resolution of 1.68A. The tertiary folding of the hK6 complexed with the inhibitor is conserved relative to the structure of the apo-protein, whereas the interaction between hK6 and the inhibitor is consistent with both the SAR and the in silico model used in the virtual screening.
