    basic FUNCTION
  • modulating substrate selectivity and catalytic activity
  • directing the localization of the catalytic enzyme to a particular subcellular compartment
  • regulatory subunit of protein phosphatase 2a consisting of a common heterodimeric coreenzyme,composed of a 36 kDa catalytic subunit (subunit c) and a 65 kDa constant regulatory subunit (pr65 or subunit a),and associating with a variety of regulatory subunits (including three families of subunits b...)

    small molecule
    protein
  • phosphorylated PIM1 binds PIN1 allowing the interaction of PPP2R5B, and dephosphorylation of PIM1 then allows for ubiquitinylation and protein degradation of PIM1
  • CLK2 phosphorylates PPP2R5B, which is a critical regulatory step in the assembly of the PP2A holoenzyme complex on AKT1 leading to dephosphorylation of both S473 and T308 AKT1 sites
