    Summary
    Enables calcium ion binding activity and kinase binding activity. Involved in several processes, including activation of phospholipase D activity; cellular response to L-glutamate; and cellular response to electrical stimulus. Located in several cellular components, including dendrite; neuronal cell body membrane; and perikaryon. Is active in glutamatergic synapse and postsynapse. Human ortholog(s) of this gene implicated in torsion dystonia 2. Orthologous to human HPCA (hippocalcin). [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.
