Transfers mannosyl residues to the hydroxyl group of serine or threonine residues. Coexpression of both POMT1 and POMT2 is necessary for enzyme activity, expression of either POMT1 or POMT2 alone is insufficient.
Specificity
Natural and recombinant Human Protein O-mannosyl-transferase 1
Subcellular Location
Endoplasmic reticulum membrane Multi-pass membrane protein
