Summary
Contributes to mannosyltransferase activity. Involved in GPI anchor biosynthetic process and fungal-type cell wall organization. Located in endoplasmic reticulum. Part of glycosylphosphatidylinositol-mannosyltransferase I complex. Orthologous to human PIGM (phosphatidylinositol glycan anchor biosynthesis class M).
