Cathepsin F (human), (recombinant)

Recombinant glycosylated procathepsin F cloned from human cDNA (NM_003793), expressed in insect cells, and purified as the active form of the enzyme. Cathepsin F, a member of the papain family of lysosomal cysteine proteases, acts upon proteins such as MHC Class II-associated invariant chain and ApoB-100. It is inhibited by the cysteine proteinase inhibitor E-64 (Prod. No. BML-EI105) and cystatin C (Prod. No. BML-SE479). It is a lysosomal protease expressed in numerous tissues, notably brain and macrophages. It functions in the immune system and is implicated in disease states such as atherosclerosis, cancer, and angiogenesis.
