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   -!- 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 IER5 (By similarity). {ECO:0000250,
CC       ECO:0000250|UniProtKB:Q9Y2T4}.
CC   -!- TISSUE SPECIFICITY: Highly expressed in brain.
CC   -!- SIMILARITY: Belongs to the phosphatase 2A regulatory subunit B family.
CC       {ECO:0000305}.
