PPP2R2A
Function
The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment. Essential for serine/threonine-protein phosphatase 2A-mediated dephosphorylation of WEE1, preventing its ubiquitin-mediated proteolysis, increasing WEE1 protein levels, and promoting the G2/M checkpoint (PubMed:33108758).
Sequence Similarities
Belongs to the phosphatase 2A regulatory subunit B family.
Tissue Specificity
Expressed in all tissues examined.
Alternative names
