Predicted to enable identical protein binding activity. Predicted to be involved in endoplasmic reticulum tubular network maintenance and positive regulation of endoplasmic reticulum tubular network organization. Predicted to act upstream of or within blood coagulation; embryonic limb morphogenesis; and regulation of chondrocyte differentiation. Predicted to be located in endoplasmic reticulum tubular network membrane and nucleoplasm. Predicted to be integral component of endoplasmic reticulum membrane. Predicted to be active in endoplasmic reticulum tubular network. Orthologous to human LNPK (lunapark, ER junction formation factor). [provided by Alliance of Genome Resources, Apr 2022]
