Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables gap junction channel activity. Involved in cell-cell signaling and gap junction-mediated intercellular transport. Acts upstream of or within olfactory behavior and sensory perception of smell. Located in plasma membrane. Part of connexin complex. Is expressed in several structures, including early conceptus; gut; male reproductive gland or organ; metanephros; and secondary oocyte. Human ortholog(s) of this gene implicated in erythrokeratodermia variabilis and erythrokeratodermia variabilis et progressiva 2. Orthologous to human GJB4 (gap junction protein beta 4).
