Description_x000D_ General description_x000D_ APOBEC3G (apolipoprotein B messenger-RNA-editing enzyme, catalytic polypeptide-like 3G) belongs to the APOBEC family of cytidine deaminases. It is expressed predominantly in cytoplasmic region. It is localized in pyramidal neurons within the gray matter of cerebral and cerebellar cortices. It has a core α-β-α fold structure for catalytic activity. The five-stranded β-sheet is surrounded on both sides by six α-helices arranged over a hydrophobic platform._x000D_ Immunogen_x000D_ DNA dC→dU-editing enzyme APOBEC-3G recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below._x000D_ Immunohistochemistry (1 paper)_x000D_ Physical form_x000D_ Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide_x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Legal Information_x000D_ Prestige Antibodies is a registered trademark of Sigma-Aldrich Co. LLC_x000D_ Biochem/physiol Actions_x000D_ APOBEC3G (apolipoprotein B mRNA editing enzyme catalytic subunit 3G) is associated with diverse biological functions such as mRNA editing, inhibiting the mobilization of retroviruses and retrotransposons, including the inhibition of human immunodeficiency virus-1 (HIV-1) replication. It can restrict HIV-1 infectivity during reverse transcription, by inserting in viral particles and deaminating the viral cDNA cytidines to uridines. The deaminated uridines mutate the DNA strand to generate stop codons for the inactivation of the virus. However, with the help of viral Vif protein HIV-1 can counteracts APOBEC3G by protosomal degradation._x000D_ Features and Benefits_x000D_ Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST73531.
