General annotation (Comments)

Function

Important for the overall degradation of proteins in lysosomes.

Catalytic activity

Hydrolysis of proteins, acting as an aminopeptidase (notably, cleaving Arg-|-Xaa bonds) as well as an endopeptidase.

Subunit structure

Composed of cathepsin H and mini chain; disulfide-linked. Cathepsin H may be split into heavy and light chain. All chains are held together by disulfide bonds.

Subcellular location

Lysosome.

Sequence similarities

Belongs to the peptidase C1 family.
