Cathepsin A/Lysosomal Carboxypeptidase A Antibody (179803) Summary

Immunogen
Mouse myeloma cell line NS0-derived recombinant human Cathepsin A/Lysosomal Carboxypeptidase A
Ala29-Tyr480 (predicted)
Accession # P10619
Specificity
Detects human Cathepsin A/Lysosomal Carboxypeptidase A in direct ELISAs and Western blots. In Western blots, detects the single chain (55 kDa) and heavy chain (32 kDa) forms of recombinant human (rh) Cathepsin A. In Western blots, less than 5% cross-reactivity with rhCathepsin B, C, D, E, L, O, S, X and Z is observed and no cross-reactivity with the light chain (20 kDa) of rhCathepsin A is observed.

Background

Cathepsin A/lyososomal carboxypeptidase A is a member of the serine carboxypeptidase family (1). Cathepsin A is a multifunctional enzyme that expresses deaminidase and esterase activities at neutral pH and carboxypeptidase activity at acidic pH. Also known as protective protein, its association with beta -galactosidase ( beta -gal) and neuraminidase is essential for beta -gal stability and neuraminidase activation in the lysosomes. Inherited deficiency of Cathepsin A causes the lysosomal storage disorder galactosialidosis, characterized by a combined secondary deficiency of beta -gal and neuraminidase. Cathepsin A is capable of hydrolyzing a variety of bioactive peptide hormones including tachykinins, indicating that extralysosomal Cathepsin A plays a role in regulation of functions of these molecules (2). Cathepsin A is synthesized as a single-chain precursor and processed into heavy (32 kDa) and light (20 kDa) chains, which are linked by disulfide bonds.
