CC -!- FUNCTION: The PR65 subunit of protein phosphatase 2A serves as a
CC scaffolding molecule to coordinate the assembly of the catalytic
CC subunit and a variable regulatory B subunit.
CC -!- SUBUNIT: PP2A consists of a common heterodimeric core enzyme, composed
CC of a 36 kDa catalytic subunit (subunit C) and a 65 kDa constant
CC regulatory subunit (PR65 or subunit A), that associates with a variety
CC of regulatory subunits. Proteins that associate with the core dimer
CC include three families of regulatory subunits B (the R2/B/PR55/B55,
CC R3/B''/PR72/PR130/PR59 and R5/B'/B56 families), the 48 kDa variable
CC regulatory subunit, viral proteins, and cell signaling molecules.
CC Interacts with IPO9. Interacts with SGO1. Interacts with RAF1.
