Description

Cathepsin A, also known as Protective Protein Cathepsin A (PPCA), is a serine carboxypeptidase that is required for correct lysosomal transportation. Cathepsin A is synthesized as a 54 kD zymogen and is processed into an enzymatically active two-chain form in lysosomes. Cathepsin A exhibits carboxypeptidase activity at acidic pH in the lysosome and acts such as deaminase and esterase at a neutral pH. It participates in the inactivation of several selected neuropeptides, which includes substance P, oxytocin, and endothelin I. Cathepsin A forms a multienzyme complex with β-galactosidase (GLB1) and neuraminidase (NEU1). It is necessary for the stability and activity for these two enzymes. Genetic defects in the CTSA gene lead to the secondary combined deficiency of GLB1 and NEU1 and cause the lysosomal storage disease galactosialidosis (GS). Cathepsin A has also been suggested to regulate chaperone-mediated autophagy through the proteolytic inactivation of Lysosome-associated membrane protein 2 (LAMP2).

Antigen Details

Structure
480 amino acids with a predicted molecular weight of 54.5 kD. Processed active form of Cathepsin A contains a 32 kD chain and a 20 kD chain. These chains form a disulfide-linked heterodimer.
Distribution
Lysosome.
Function
Cathepsin A is a serine carboxypeptidase required for the activation and stabilization of β-galactosidase and neuraminidase in the lysosomal compartment. Defects in the gene can cause the lysosomal storage disorder galactosialidosis.
Interaction
Cathepsin A interacts with CTNNBIP1, GABARAP, ELN, and VAPA.
