Term Name:	dol-P-Man:GlcN-acyl-PI alpha-1,4-mannosyltransferase activity
Synonyms:	glycolipid 1,4-alpha-mannosyltransferase activity, glycosylphosphatidylinositol-mannosyltransferase I activity, GPI-MT-I activity
Definition:	Catalysis of the transfer of an alpha-D-mannosyl residue from dolichol-P-mannose to GlcN-acyl-PI, forming an alpha-(1->4)-D-mannosyl-GlcN linkage. This transfers the first mannose to the GPI precursor.
