Product Background


Gene summary
APOBEC3G (Apolipoprotein B MRNA Editing Enzyme Catalytic Subunit 3G) is a Protein Coding gene. Diseases associated with APOBEC3G include hepatitis b and hiv-1. Among its related pathways are Infectious disease and Integrated Breast Cancer Pathway. GO annotations related to this gene include protein homodimerization activity and hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in cyclic amidines. An important paralog of this gene is AICDA. This gene is a member of the cytidine deaminase gene family. It is one of seven related genes or pseudogenes found in a cluster, thought to result from gene duplication, on chromosome 22. Members of the cluster encode proteins that are structurally and functionally related to the C to U RNA-editing cytidine deaminase APOBEC1. It is thought that the proteins may be RNA editing enzymes and have roles in growth or cell cycle control. The protein encoded by this gene has been found to be a specific inhibitor of human immunodeficiency virus-1 (HIV-1) infectivity.
Antigen Description
APOBEC3G (apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3G) is a human enzyme encoded by the APOBEC3G gene that belongs to the APOBEC superfamily of proteins. This family of proteins has been suggested to play an important role in innate anti-viral immunity. APOBEC3G belongs to the family of cytidine deaminases that catalyze the deamination of cytidine to uridine in the single stranded DNA substrate. The C-terminal domain of A3G renders catalytic activity, several NMR and crystal structures explain the substrate specificity and catalytic activity APOBEC3G mRNA is expressed in certain cells, referred to as non-permissive cells, in which HIV-1 cannot properly infect and replicate in the absence of Vif. Such cells include physiologically relevant primary CD4 T lymphocytes and macrophages. The encapsidation of APOBEC3G into HIV-1 virions is very important for the spread of APOBEC3G and the exertion of anti-retroviral activity. Encapsidation of APOBEC3G may occur by at least the following four proposed mechanisms (Figure 3): 1. Non-specific packaging of APOBEC3G 2. APOBEC3G interaction with host RNA 3. APOBEC3G interaction with viral RNA 4. Interaction of APOBEC3G with HIV-1 Gag proteins. Only the latter two mechanisms have been extensively confirmed.
