Summary: Predicted to enable oxysterol binding activity and protein sequestering activity. Acts upstream of or within several processes, including ear morphogenesis; negative regulation of fat cell differentiation; and negative regulation of lipid biosynthetic process. Predicted to be part of SREBP-SCAP-Insig complex. Predicted to be active in endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; eye; ganglia; telencephalon ventricular layer; and vibrissa. Orthologous to human INSIG1 (insulin induced gene 1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
