Summary: Predicted to enable several functions, including ATP binding activity; ATP hydrolysis activity; and alkali metal ion binding activity. Involved in several processes, including locomotory exploration behavior; neurotransmitter uptake; and response to auditory stimulus. Acts upstream of or within several processes, including forebrain development; regulation of blood circulation; and regulation of muscle contraction. Located in T-tubule; cell projection; and neuronal cell body. Part of protein-containing complex. Is active in cell surface; endoplasmic reticulum; and plasma membrane. Is expressed in several structures, including genitourinary system; heart; musculature; nervous system; and sensory organ. Used to study familial hemiplegic migraine 2. Human ortholog(s) of this gene implicated in alternating hemiplegia of childhood; electroclinical syndrome (multiple); hypertension; and migraine with aura (multiple). Orthologous to human ATP1A2 (ATPase Na+/K+ transporting subunit alpha 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.
