    Summary
    Enables calcium channel activity. Acts upstream of or within several processes, including learning or memory; neuron cellular homeostasis; and regulation of synaptic plasticity. Located in membrane. Is active in postsynapse and presynapse. Is expressed in lens; lens epithelium; and lens fiber. Orthologous to human SLC24A2 (solute carrier family 24 member 2).

    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.
