Description

Predicted to be involved in cell communication. Predicted to localize to connexin complex and integral component of membrane. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 2B; autosomal recessive nonsyndromic deafness 1A; erythrokeratodermia variabilis; and erythrokeratodermia variabilis et progressiva 1. Is expressed in EVL; periderm; pharynx; and sensory system. Orthologous to human GJB3 (gap junction protein beta 3).
