Predicted to enable inward rectifier potassium channel activity. Predicted to be involved in potassium ion import across plasma membrane and regulation of ion transmembrane transport. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in Leber congenital amaurosis 16 and snowflake vitreoretinal degeneration. Orthologous to human KCNJ13 (potassium inwardly rectifying channel subfamily J member 13). [provided by Alliance of Genome Resources, Apr 2022]
