Enables ATP hydrolysis activity; protein kinase binding activity; and syntaxin-1 binding activity. Acts upstream of or within potassium ion transport. Located in myelin sheath. Is expressed in several structures, including alimentary system; central nervous system; eye; genitourinary system; and integumental system. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy. Orthologous to human NSF (N-ethylmaleimide sensitive factor, vesicle fusing ATPase).
