General annotation (Comments)

Function	Involved in antiviral defense. May impair virus budding by disrupting lipid rafts at the plasma membrane, a feature which is essential for the budding process of many viruses. Acts through binding with and inactivating FPPS, an enzyme involved in synthesis of cholesterol, farnesylated and geranylated proteins, ubiquinones dolichol and heme. Plays a major role in the cell antiviral state induced by type I and type II interferon. Displays antiviral effect against HIV-1 virus, hepatitis C virus, human cytomegalovirus, and aphaviruses, but not vesiculovirus. Ref.2 Ref.7 Ref.10 Ref.11 Ref.13
Cofactor	Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.
Subunit structure	Interacts with FPPS. Ref.12
Subcellular location	Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side. Golgi apparatus. Note: Probably associates with the cytosolic side of the endoplasmic reticulum. Infection with human cytomegalovirus (HCMV) causes relocation to the Golgi apparatus and to cytoplasmic vacuoles which also contain HCMV proteins glycoprotein B and pp28. Ref.2 Ref.10
Induction	By interferon type I, type II and bacterial lipopolysaccharides (LPS). Little or no induction by IFNG/IFN-gamma is observed in monocytic cell lines. Induced by infection with human cytomegalovirus (HMCV), hepatitis C virus, yellow fever virus and Sendai virus, presumably through type I interferon pathway. Ref.1 Ref.2 Ref.6 Ref.7 Ref.8 Ref.9
Miscellaneous	Up-regulated in atherosclerosis. Latent viruses like HCMV may be involved in atherogenesis by initiating local inflammation. This may induce up-regulation of antiviral gene RSAD2, which modulates lipids synthesis, and thus could play a role in abnormal lipid accumulation leading to atherosclerosis.
Sequence similarities	Belongs to the RSAD2 family.
