| 1556992 | Gjb4 | gap junction protein, beta 4 | 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 gut; male reproductive gland or organ; metanephros; nasal epithelium; 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).
