    Summary
    Predicted to enable voltage-gated calcium channel activity. Predicted to be involved in several processes, including calcium ion transport; flagellated sperm motility; and sperm capacitation. Predicted to be located in sperm flagellum. Predicted to be part of CatSper complex. Orthologous to human CATSPER2 (cation channel sperm associated 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.
