Enables ceramide glucosyltransferase activity. Involved in several processes, including cornified envelope assembly; glucosylceramide biosynthetic process; and skin development. Predicted to be located in Golgi membrane. Predicted to be integral component of membrane. Predicted to be active in membrane. Is expressed in several structures, including blastocyst; brain; early embryo; liver; and oocyte. Orthologous to human UGCG (UDP-glucose ceramide glucosyltransferase).
