Predicted to enable aldo-keto reductase (NADP) activity; potassium channel regulator activity; and transmembrane transporter binding activity. Involved in neuromuscular process. Acts upstream of or within hematopoietic progenitor cell differentiation. Located in axon and postsynaptic density. Is expressed in several structures, including central nervous system; genitourinary system; hemolymphoid system; intestine; and sensory organ. Used to study chromosome 1p36 deletion syndrome. Orthologous to human KCNAB2 (potassium voltage-gated channel subfamily A regulatory beta subunit 2). [provided by Alliance of Genome Resources, Apr 2022]
