Predicted to enable gap junction channel activity. Acts upstream of or within cell morphogenesis; lens development in camera-type eye; and organ growth. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. Predicted to be part of connexin complex. Is expressed in lens; lens epithelium; lens equatorial epithelium; lens vesicle; and retina. Orthologous to human GJE1 (gap junction protein epsilon 1). [provided by Alliance of Genome Resources, Apr 2022]
