Cathepsin A

Cathepsin A is an is_associated_with::enzyme that is classified both as a is_associated_with::cathepsin and a is_associated_with::carboxypeptidase. In humans, it is encoded by the CTSA is_associated_with::gene.

Function
This gene encodes a glycoprotein that associates with lysosomal enzymes is_associated_with::beta-galactosidase and is_associated_with::neuraminidase to form a complex of high-molecular-weight multimers. The formation of this complex provides a protective role for stability and activity. It is protective for β-galactosidase and is_associated_with::neuraminidase.

Clinical significance
Deficiencies in this gene are linked to multiple forms of is_associated_with::galactosialidosis.

Interactions
Cathepsin A has been shown to interact with is_associated_with::NEU1.
