Enables several functions, including identical protein binding activity; sulfonylurea receptor activity; and syntaxin binding activity. Contributes to cation channel activity. Involved in potassium ion import across plasma membrane; response to ATP; and response to xenobiotic stimulus. Located in T-tubule; acrosomal vesicle; and mitochondrion. 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; and hypertrichotic osteochondrodysplasia Cantu type. Orthologous to human ABCC9 (ATP binding cassette subfamily C member 9). [provided by Alliance of Genome Resources, Apr 2022]
