Members of this protein family, uncommon and rather sporadically distributed, are found almost always in the same genomes as members of family TIGR03662, and frequently as a nearby gene. Members show some N-terminal sequence similarity with pfam02366, dolichyl-phosphate-mannose-protein mannosyltransferase. The few invariant residues in this family, found toward the N-terminus, include a dipeptide DE, a tripeptide HGP, and two different Arg residues. Up to three members may be found in a genome. The function is unknown.
