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 act upstream of or within ion transport. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. Predicted to be part of voltage-gated potassium channel complex. Orthologous to human LRRC55 (leucine rich repeat containing 55). [provided by Alliance of Genome Resources, Apr 2022]
