Summary: Predicted to enable kinase binding activity; phosphoprotein phosphatase activity; and protein phosphatase activator activity. Predicted to be involved in negative regulation of lipid kinase activity; negative regulation of protein localization to plasma membrane; and protein dephosphorylation. Located in M band and Z disc. Is expressed in several structures, including brain; gonad; hemolymphoid system gland; liver; and neural retina. Orthologous to human PPP2R5A (protein phosphatase 2 regulatory subunit B'alpha).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
