CC -!- FUNCTION: Stabilizes the HMG-CoA reductase HMG2 by preventing its HRD1-
CC dependent degradation. Binds directly to the sterol-sensing domain
CC (SSD)-containing transmembrane region of HMG2, promoting its folding to
CC protect it from degradation. {ECO:0000269|PubMed:16270032}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:14562095, ECO:0000269|PubMed:16270032}; Multi-pass
CC membrane protein {ECO:0000269|PubMed:14562095,
CC ECO:0000269|PubMed:16270032}.
CC -!- MISCELLANEOUS: Present with 3390 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the INSIG family. {ECO:0000305}.
