Enables mannosyltransferase activity. Involved in GPI anchor biosynthetic process. Located in endoplasmic reticulum membrane. Part of mannosyltransferase complex.
SGD Description
Essential component of GPI-mannosyltransferase II; complex is responsible for second mannose addition to GPI precursors as a partner of Gpi18p; required for maturation of Gas1p and Pho8p; has synthetic genetic interactions with secretory pathway genes
