Summary
Enables ankyrin binding activity; calcium:sodium antiporter activity; and transmembrane transporter binding activity. Involved in several processes, including cellular response to caffeine; metal ion transport; and vascular associated smooth muscle contraction. Acts upstream of or within several processes, including embryonic organ development; metal ion transport; and negative regulation of protein serine/threonine kinase activity. Located in several cellular components, including T-tubule; basolateral plasma membrane; and postsynaptic density. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; heart; and nose. Human ortholog(s) of this gene implicated in hypertension. Orthologous to human SLC8A1 (solute carrier family 8 member A1). [provided by Alliance of Genome Resources, Nov 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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (D) differs in several internal exons, compared to variant A. This variant is represented as non-coding because the use of the 5'-most expected translation start codon, as used in variant A, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
