The product of this gene belongs to the phosphatase 2A regulatory subunit B family. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes an epsilon isoform of the regulatory subunit B56 subfamily.
Alternate names: PP2A B subunit B'epsilon isoform, PP2A B subunit B56 epsilon isoform, PP2A B subunit PR61 epsilon isoform, PP2A B subunit R5 epsilon isoform, Protein phosphatase 2A, Serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit epsilon isoform
