Prototype Foamy Virus Integrase Displays Unique Biochemical Activities among Retroviral Integrases [PDF]

open access: yesBiomolecules, 2021
Integrases of different retroviruses assemble as functional complexes with varying multimers of the protein. Retroviral integrases require a divalent metal cation to perform one-step transesterification catalysis.

Weight gain and integrase inhibitors. [PDF]

open access: yesCurrent Opinion in Infectious Diseases, 2019
PURPOSE OF REVIEW Weight gain and obesity among people living with HIV (PLWH) is a serious problem that occurs often after initiation of antiretroviral therapy but may be worse with integrase strand transfer inhibitors (INSTIs).

Structural basis of second-generation HIV integrase inhibitor action and viral resistance

open access: yesScience, 2020
Strengths and weaknesses of an HIV drug Retroviruses replicate by inserting a copy of their RNA, which has been reverse transcribed into DNA, into the host genome. This process involves the intasome, a nucleoprotein complex comprising copies of the viral

PP2A Phosphatase as an Emerging Viral Host Factor

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Protein phosphatase 2A (PP2A) is one of the most ubiquitous cellular proteins and is responsible for the vast majority of Ser/Thr phosphatase activity in eukaryotes. PP2A is a heterotrimer, and its assembly, intracellular localization, enzymatic activity,

Going beyond Integration: The Emerging Role of HIV-1 Integrase in Virion Morphogenesis

open access: yesViruses, 2020
The HIV-1 integrase enzyme (IN) plays a critical role in the viral life cycle by integrating the reverse-transcribed viral DNA into the host chromosome. This function of IN has been well studied, and the knowledge gained has informed the design of small ...

Reduced efficacy of HIV-1 integrase inhibitors in patients with drug resistance mutations in reverse transcriptase

open access: yesNature Communications, 2020
Little is known about the impact of pretreatment drug resistance (PDR) on the efficacy of second generation integrase inhibitors. We sequenced pretreatment plasma specimens from the ADVANCE trial (NCT03122262).

The Drug-Induced Interface That Drives HIV-1 Integrase Hypermultimerization and Loss of Function

open access: yesmBio, 2023
Allosteric HIV-1 integrase (IN) inhibitors (ALLINIs) are an emerging class of small molecules that disrupt viral maturation by inducing the aberrant multimerization of IN. Here, we present cocrystal structures of HIV-1 IN with two potent ALLINIs, namely,

Integrase and integration: biochemical activities of HIV-1 integrase [PDF]

open access: yesRetrovirology, 2008
Integration of retroviral DNA is an obligatory step of retrovirus replication because proviral DNA is the template for productive infection. Integrase, a retroviral enzyme, catalyses integration. The process of integration can be divided into two sequential reactions.

HIV-1 integrase polymorphisms are associated with prior antiretroviral drug exposure

open access: yesRetrovirology, 2009
In a recent summary of integrase sequences, primary integrase inhibitor mutations were rare. In a review of integrase inhibitor-naïve Australian HIV-1 sequences, primary mutations were not identified, although the accessory mutation G140S was detected. A

Genetic Diversity and Low Therapeutic Impact of Variant-Specific Markers in HIV-1 Pol Proteins

open access: yesFrontiers in Microbiology, 2022
The emergence and spread of new HIV-1 variants pose a challenge for the effectiveness of antiretrovirals (ARV) targeting Pol proteins. During viral evolution, non-synonymous mutations have fixed along the viral genome, leading to amino acid (aa) changes ...
