CC -!- FUNCTION: Alpha-1,2-mannosyltransferase involved in
CC glycosylphosphatidylinositol-anchor biosynthesis. Transfers a fourth
CC mannose to trimannosyl-GPIs during GPI precursor assembly. The presence
CC of a fourth mannose in GPI is essential in fungi (By similarity).
CC {ECO:0000250}.
CC -!- PATHWAY: Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor
CC biosynthesis.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 22 family. PIGZ
CC subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAH01341.1; Type=Erroneous initiation; Evidence={ECO:0000305};
