Claim: The product of PPP2R5A belongs to the phosphatase 2A regulatory subunit B family and this subunit might modulate substrate selectivity and catalytic activity, also the PPP2R5A  encodes alpha isoform of the regulatory subunit B56 subfamily.
Evidence: The product of this gene belongs to the phosphatase 2A regulatory subunit B family. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes an alpha isoform of the regulatory subunit B56 subfamily.
