Protein O-mannosyltransferase involved in O-glycosylation which is essential for cell wall rigidity. Forms a heterodimeric complex with PMT5 and more rarely with PMT1 to transfer mannose from Dol-P-mannose to Ser or Thr residues on proteins. Seems to have redundant activity to PMT2. Source: Recombinant protein corresponding to aa304-602 from Saccharomyces cerevisiae Dolichyl-phosphate-mannose--protein mannosyltransferase 3, fused to 6X His-Tag at N-terminal, expressed in E.coli.
