Automated description from the Alliance of Genome Resources (Release 3.0)
Predicted to have structural molecule activity. Involved in apical junction assembly; neuronal action potential propagation; and tight junction organization. Localizes to several cellular components, including bicellular tight junction; nucleus; and plasma membrane. Human ortholog(s) of this gene implicated in renal hypomagnesemia 5 with ocular involvement. Is expressed in several structures, including cerebellum; gonad; metanephros; midbrain; and submandibular gland. Orthologous to human CLDN19 (claudin 19).
