Gene: Gjb4 (gap junction protein, beta 4) Rattus norvegicus
Symbol: Gjb4
Name: gap junction protein, beta 4
Description: Predicted to have gap junction channel activity. Predicted to be involved in several processes, including gap junction-mediated intercellular transport; olfactory behavior; and sensory perception of smell. Predicted to localize to connexin complex; integral component of plasma membrane; and nuclear lumen. 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); INTERACTS WITH 3,7-dihydropurine-6-thione; ammonium chloride; bisphenol A.
Type: protein-coding
Also known as: Cnx30.3; Cnx30.3o; connexin 30.3; connexin 30.3o; connexin b; connexin-30.3; Cx30.3; Cx30.3o; Cxnb; gap junction beta-4 protein; gap junction membrane channel protein beta 4; gap junction protein beta 4; Gjb4o
