CC -!- FUNCTION: The B regulatory subunit might modulate substrate selectivity
CC and catalytic activity, and also might direct the localization of the
CC catalytic enzyme to a particular subcellular compartment.
CC {ECO:0000250}.
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 (By
CC similarity). Interacts with TOMM22 (By similarity). Interacts with IER5
CC (via N- and C-terminal regions) (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P36877, ECO:0000250|UniProtKB:Q00005}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Cytoplasm, cytoskeleton
CC {ECO:0000250}. Membrane {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the phosphatase 2A regulatory subunit B family.
CC {ECO:0000305}.
