    Summary
    Enables protein phosphatase 2A binding activity and tau protein binding activity. Predicted to be involved in protein dephosphorylation. Predicted to act upstream of or within response to morphine. Predicted to be part of protein phosphatase type 2A complex. Predicted to be active in cytosol and glutamatergic synapse. Orthologous to human PPP2R2A (protein phosphatase 2 regulatory subunit Balpha). [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.
