CC -!- FUNCTION: Alpha-1,2-mannosyltransferase required for cell wall
CC integrity. Responsible for addition of the first alpha-1,2-linked
CC mannose to form the branches on the mannan backbone of
CC oligosaccharides. Addition of alpha-1,2-mannose is required for
CC stabilization of the alpha-1,6-mannose backbone and hence regulates
CC mannan fibril length; and is important for both immune recognition and
CC virulence. {ECO:0000269|PubMed:23633946}.
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000250}; Single-
CC pass type II membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the MNN1/MNT family. {ECO:0000305}.
