Model Structure of Human APOBEC3G
BACKGROUND APOBEC3G (apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G) has antiretroviral activity associated with the hypermutation of viral DNA through cytosine deamination. APOBEC3G has two cytosine deaminase (CDA) domains; the catalytically inactive amino-terminal domain of APOBEC3G (N-CDA) carries the Vif interaction domain. There is no 3-D structure of APOBEC3G solved b...

The motivation of the author in writing...
متن کاملHypermutation of an ancient human retrovirus by APOBEC3G.
Human endogenous retroviruses (HERVs) comprise approximately 8% of the human genome, but all are remnants of ancient retroviral infections and harbor inactivating mutations that render them replication defective. Nevertheless, as viral "fossils," HERVs may provide insights into ancient retrovirus-host interactions and their evolution. Indeed, one endogenous retrovirus [HERV-K(HML-2)], which has...
متن کاملThe Restriction of Zoonotic PERV Transmission by Human APOBEC3G
The human APOBEC3G protein is an innate anti-viral factor that can dominantly inhibit the replication of some endogenous and exogenous retroviruses. The prospects of purposefully harnessing such an anti-viral defense are under investigation. Here, long-term co-culture experiments were used to show that porcine endogenous retrovirus (PERV) transmission from pig to human cells is reduced to nearl...
متن کاملComputational Model and Dynamics of Monomeric Full-Length APOBEC3G
APOBEC3G (A3G) is a restriction factor that provides innate immunity against HIV-1 in the absence of viral infectivity factor (Vif) protein. However, structural information about A3G, which can aid in unraveling the mechanisms that govern its interactions and define its antiviral activity, remains unknown. Here, we built a computer model of a full-length A3G using docking approaches and molecul...
