POMT2 is an integral membrane protein of the endoplasmic reticulum (ER) that shares significant sequence similarity with a family of protein O-mannosyltransferases of S. cerevisiae.POMT2 encodes an integral membrane protein of the endoplasmic reticulum (ER) that shares significant sequence similarity with a family of protein O-mannosyltransferases of S. cerevisiae. For additional background information, see POMT1 (MIM 607423).[supplied by OMIM]. Sequence Note: This RefSeq record was created from transcript and genomic sequence data because no single transcript was available for the full length of the gene. The extent of this transcript is supported by transcript alignments.
