Summary: Enables several functions, including identical protein binding activity; potassium channel activator activity; and sulfonylurea receptor activity. Involved in potassium ion import across plasma membrane; response to ATP; and response to xenobiotic stimulus. Located in T-tubule and acrosomal vesicle. Part of inward rectifying potassium channel. Biomarker of Parkinsonism; hypertension; and sciatic neuropathy. Human ortholog(s) of this gene implicated in dilated cardiomyopathy; dilated cardiomyopathy 1O; familial atrial fibrillation; hypertrichotic osteochondrodysplasia Cantu type; and intellectual disability and myopathy syndrome. Orthologous to human ABCC9 (ATP binding cassette subfamily C member 9). [provided by Alliance of Genome Resources, Jul 2025]

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.
