Automated description from the Alliance of Genome Resources (Release 7.0.0)
Predicted to enable structural molecule activity. Acts upstream of or within apical junction assembly; neuronal action potential propagation; and tight junction organization. Located in several cellular components, including bicellular tight junction; nucleus; and plasma membrane. Is expressed in several structures, including alimentary system; cerebellum; gonad; metanephros; and midbrain. Human ortholog(s) of this gene implicated in renal hypomagnesemia 5 with ocular involvement. Orthologous to human CLDN19 (claudin 19).
