CATB Rabbit Polyclonal Antibody, 50ul[BT-AP06919]

Catalytic activity:Hydrolysis of proteins with broad specificity for peptide bonds. Preferentially cleaves -Arg-Arg-|-Xaa bonds in small molecule substrates (thus differing from cathepsin L). In addition to being an endopeptidase| shows peptidyl-dipeptidase activity| liberating C-terminal dipeptides.|Thiol protease which is believed to participate in intracellular degradation and turnover of proteins. Has also been implicated in tumor invasion and metastasis.|Belongs to the peptidase C1 family.|subcellular location:Identified by mass spectrometry in melanosome fractions from stage I to stage IV.|subunit:Dimer of a heavy chain and a light chain cross-linked by a disulfide bond.|
