Predicted to enable cholesterol binding activity and ubiquitin protein ligase binding activity. Predicted to be involved in SREBP signaling pathway; negative regulation of lipid biosynthetic process; and ubiquitin-dependent ERAD pathway. Predicted to act upstream of or within cholesterol metabolic process. Predicted to be located in several cellular components, including cytosol; endoplasmic reticulum; and membrane raft. Predicted to be part of protein-containing complex. Predicted to be active in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 18. Orthologous to human ERLIN2 (ER lipid raft associated 2). [provided by Alliance of Genome Resources, Apr 2022]
