Summary: Enables phosphoprotein phosphatase activity. Involved in protein dephosphorylation. Predicted to be located in postsynapse and sarcolemma. Predicted to be part of calcineurin complex. Predicted to be active in several cellular components, including Schaffer collateral - CA1 synapse; hippocampal mossy fiber to CA3 synapse; and parallel fiber to Purkinje cell synapse. Biomarker of traumatic brain injury. Human ortholog(s) of this gene implicated in Alzheimer's disease and dilated cardiomyopathy. Orthologous to human PPP3R1 (protein phosphatase 3 regulatory subunit B, alpha). [provided by Alliance of Genome Resources, Dec 2024]

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.
