靶點詳情

  • 功能：
    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.

    2. The gene signature of OPA1, CTSA, NDUFA1, STK10 and PRDX1 was able to identify patients post-implant with a sensitivity of 91% and a specificity of 86% in discrimination between post-implant group and healthy controls. PMID: 27177495
    3. Galactosialidosis is a rare lysosomal storage disease caused by a combined deficiency of GM1 beta-galactosidase (beta-gal) and neuraminidase secondary to a defect of a lysosomal enzyme protective protein/cathepsin A (PPCA) and mutation in CTSA gene. PMID: 26259553
