Descripción

General description

Research area: Cell signaling

Native Cathepsin H, from the human liver, is the only cathepsin with mono-aminopeptidase activity.

Application

Cathepsin H has been used to determine the potential of aziridinyl peptides to act as inhibitors of this protein and potentially explore their therapeutic applications.

Biochem/physiol Actions

Cathepsin H, derived from human liver, serves dual functions as both an aminopeptidase and an endopeptidase. It plays a significant role in the catabolism of proteins within lysosomes. Cathepsin H is classified as an endoaminopeptidase because it can hydrolyze proteins, N-terminal substituted proteins, amino acid derivatives, and peptides with different chain lengths and N-terminal free amino acid derivatives. This protein is also observed to exhibit amidase and esterase activity.

Packaging
