Comments
Comment typeDescription
FunctionRequired for proper folding and/or the stability of a subset of proteins in the endoplasmic reticulum. Aids the autocatalytic processing of PRB1. Component of glycosylphosphatidylinositol-mannosyltransferase 1 which transfers the first of the 4 mannoses in the GPI-anchor precursors during GPI-anchor biosynthesis. Probably acts by stabilizing the mannosyltransferase GPI14. {ECO:0000269|PubMed:15635094, ECO:0000269|PubMed:16418276, ECO:0000269|PubMed:9649520}.
