产品介绍background:
The protein encoded by this gene is a lysosomal cysteine proteinase that plays a major role in intracellular protein catabolism. Its substrates include collagen and elastin, as well as alpha-1 protease inhibitor, a major controlling element of neutrophil elastase activity. The encoded protein has been implicated in several pathologic processes, including myofibril necrosis in myopathies and in myocardial ischemia, and in the renal tubular response to proteinuria. This protein, which is a member of the peptidase C1 family, is a dimer composed of disulfide-linked heavy and light chains, both produced from a single protein precursor. At least two transcript variants encoding the same protein have been found for this gene.

Function:
Important for the overall degradation of proteins in lysosomes.

Subunit:
Dimer of a heavy and a light chain linked by disulfide bonds.

Subcellular Location:
Lysosome.

Similarity:
Belongs to the peptidase C1 family.

P06797
