F09E5.11 encodes a divergent ortholog of S. cerevisiae VPH2/VMA12; likeVPH2, F09E5.11 may be required for vacuolar proton-translocating ATPase(V-ATPase) assembly in the endoplasmic reticulum.
Predicted to be involved in vacuolar proton-transporting V-type ATPase complex assembly. Predicted to be located in endomembrane system. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type IIp. Is an ortholog of human TMEM199 (transmembrane protein 199).
