Protein
Lysosomal protective protein
Gene
CTSA, PPGB
Organism
Bos taurus (Bovine)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

Protective protein appears to be essential for both the activity of beta-galactosidase and neuraminidase, it associates with these enzymes and exerts a protective function necessary for their stability and activity. This protein is also a carboxypeptidase and can deamidate tachykinins By similarity.

Catalytic activityi

Release of a C-terminal amino acid with broad specificity.
