    basic FUNCTION
  • galactosidase, associated with esterase, deamidase, serine carboxypeptidase, cathepsin A activity, activity on selected neuropeptides, catalytic function distinct from the protective function
  • serine carboxypeptidase activity triggering the degradation of the lysosome-associated membrane protein type 2a (Cuervo 2003)
  • carboxypeptidase that can deamidate tachykinins (Galjart 1991)
    • CELLULAR PROCESS

    a component
  • complexing with beta-galactosidase and neuramidase, providing a protective role for stability and activity
