CC -!- FUNCTION: Regulates the biosynthesis of dolichol phosphate-mannose.
CC Regulatory subunit of the dolichol-phosphate mannose (DPM) synthase
CC complex; essential for the ER localization and stable expression of
CC DPMS1. {ECO:0000269|PubMed:21558543}.
CC -!- PATHWAY: Protein modification; protein glycosylation. {ECO:0000305}.
CC -!- SUBUNIT: Component of the dolichol-phosphate mannose (DPM) synthase
CC complex composed of DPMS1, DPMS2 and DPMS3; in the complex interacts
CC directly with DPMS3. Associates with the GPI-GlcNAc transferase (GPI-
CC GnT) complex. {ECO:0000269|PubMed:21558543}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:21558543}; Multi-pass membrane protein
CC {ECO:0000255}. Note=May serve as regulatory subunit and membrane anchor
CC for DPMS1. {ECO:0000269|PubMed:21558543}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC conditions. {ECO:0000269|PubMed:21558543}.
CC -!- SIMILARITY: Belongs to the DPM2 family. {ECO:0000305}.
