CC -!- FUNCTION: Phosphatase 2A affects a variety of biological processes in
CC the cell such as transcription, cell cycle progression and cellular
CC morphogenesis, and provides an initial identification of critical
CC substrates for this phosphatase. The regulatory subunit may direct the
CC catalytic subunit to distinct, albeit overlapping, subsets of
CC substrates (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: PP2A exists in several trimeric forms, all of which consist of
CC a core composed of a catalytic subunit associated with a 65 kDa (PR65)
CC (Subunit A) and a 55 kDa (PR55) (Subunit B) regulatory subunit.
CC -!- INTERACTION:
CC Q9UT08; P13681: dis2; NbExp=10; IntAct=EBI-16132377, EBI-4320127;
CC Q9UT08; Q12702: pab1; NbExp=6; IntAct=EBI-16132377, EBI-16132256;
CC Q9UT08; Q10428: par1; NbExp=6; IntAct=EBI-16132377, EBI-989357;
CC -!- DOMAIN: Each HEAT repeat appears to consist of two alpha helices joined
CC by a hydrophilic region, the intrarepeat loop. The repeat units may be
CC arranged laterally to form a rod-like structure.
CC -!- SIMILARITY: Belongs to the phosphatase 2A regulatory subunit A family.
CC {ECO:0000305}.
