Predicted to enable several functions, including calcium ion binding activity; protein N-terminus binding activity; and transmembrane transporter binding activity. Predicted to be involved in positive regulation of action potential and regulation of potassium ion transmembrane transport. Predicted to act upstream of or within potassium ion transmembrane transport and regulation of ion transmembrane transport. Part of voltage-gated potassium channel complex. Is expressed in several structures, including brain; ganglia; intestine smooth muscle circular layer; spinal cord; and testis. Orthologous to human KCNIP1 (potassium voltage-gated channel interacting protein 1). [provided by Alliance of Genome Resources, Apr 2022]
