Predicted to enable protein transmembrane transporter activity. Predicted to be involved in SRP-dependent cotranslational protein targeting to membrane and posttranslational protein targeting to membrane, translocation. Predicted to act upstream of or within liver development; multicellular organism aging; and nitrogen compound metabolic process. Predicted to be located in endoplasmic reticulum and membrane. Predicted to be part of Sec62/Sec63 complex. Human ortholog(s) of this gene implicated in polycystic liver disease. Orthologous to human SEC63 (SEC63 homolog, protein translocation regulator).
