    Summary
    Enables voltage-gated calcium channel activity. Involved in calcium ion transport. Acts upstream of or within fertilization; flagellated sperm motility; and sperm capacitation. Located in sperm flagellum. Part of CatSper complex. Orthologous to human CATSPER2 (cation channel sperm associated 2). [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.
