CC   -!- FUNCTION: The B regulatory subunit may modulate substrate selectivity
CC       and catalytic activity, and also may direct the localization of the
CC       catalytic enzyme to a particular subcellular compartment.
CC       {ECO:0000250}.
CC   -!- SUBUNIT: PP2A consists of a common heteromeric enzyme, composed of a
CC       catalytic subunit (subunits C), a constant regulatory subunit (subunit
CC       A), and a variety of regulatory subunits such as subunits B (the
CC       R2/B/PR55/B55, R3/B''/PR72/PR130/PR59 and R5/B'/B56 families).
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the phosphatase 2A regulatory subunit B family.
CC       {ECO:0000305}.
