HIV-1 Vpr activates the G2checkpoint through manipulation of the ubiquitin proteasome system (2007)

DeHart, Jason L, Zimmerman, Erik S, Ardon, Orly, Monteiro-Filho, Carlos MR, Argañaraz, Enrique R, Planelles, Vicente

Abstract HIV-1 Vpr is a viral accessory protein that activates ATR through the induction of DNA replication stress. ATR activation results in cell cycle arrest in G 2 and induction of apoptosis. In...

HIV-1 Vpr-Induced Apoptosis Is Cell Cycle Dependent and Requires Bax but Not ANT (2006)

Joshua L. Andersen, Jason L. DeHart, Erik S. Zimmerman, Orly Ardon, Baek Kim, Guillaume Jacquot, ...

The HIV-1 accessory protein viral protein R (Vpr) causes G2 arrest and apoptosis in infected cells. We previously identified the DNA damage–signaling protein ATR as the cellular factor that...

Human Immunodeficiency Virus Type 1 Vpr-Mediated G2 Arrest Requires Rad17 and Hus1 and Induces Nuclear BRCA1 and γ-H2AX Focus Formation

Zimmerman, Erik S., Chen, Junjie, Andersen, Joshua L., Ardon, Orly, DeHart, Jason L., Blackett, Jana, ...

Eukaryotic cells have evolved a complex mechanism for sensing DNA damage during genome replication. Activation of this pathway prevents entry into mitosis to allow for either DNA repair or, in the...

The Ataxia Telangiectasia-Mutated and Rad3-Related Protein Is Dispensable for Retroviral Integration

DeHart, Jason L., Andersen, Joshua L., Zimmerman, Erik S., Ardon, Orly, An, Dong Sung, Blackett, Jana, ...

Integration into the host cell DNA is an essential part of the retroviral life cycle and is required for the productive replication of a retrovirus. Retroviral integration involves cleavage of the...

Induction of G2 Arrest and Binding to Cyclophilin A Are Independent Phenotypes of Human Immunodeficiency Virus Type 1 Vpr

Ardon, Orly, Zimmerman, Erik S., Andersen, Joshua L., DeHart, Jason L., Blackett, Jana, Planelles, Vicente

Cyclophilin A (CypA) is a member of a family of cellular proteins that share a peptidyl prolyl cis-trans isomerase (PPIase) activity. CypA was previously reported to be required for the biochemical...

Human Immunodeficiency Virus Type 1 Vif Induces Cell Cycle Delay via Recruitment of the Same E3 Ubiquitin Ligase Complex That Targets APOBEC3 Proteins for Degradation▿ ‡

DeHart, Jason L., Bosque, Alberto, Harris, Reuben S., Planelles, Vicente

Human immunodeficiency virus type 1 (HIV-1) Vif recruits a Cullin 5 ubiquitin ligase that targets APOBEC3 proteins for degradation. Recently, Vif has also been shown to induce cell cycle disturbance...
