Predicted to enable potassium channel activator activity; transmembrane transporter binding activity; and voltage-gated potassium channel activity. Predicted to be involved in positive regulation of voltage-gated potassium channel activity and potassium ion transmembrane transport. Predicted to be part of voltage-gated potassium channel complex. Orthologous to human LRRC38 (leucine rich repeat containing 38). [provided by Alliance of Genome Resources, Apr 2022]
