A reverse transcriptase ribozyme
A highly evolved RNA polymerase ribozyme was found to also be capable of functioning as a reverse transcriptase, an activity that has never been demonstrated before for RNA. This activity is thought to have been crucial for the transition from RNA to DNA

Retroviral restriction factor APOBEC3G delays the initiation of DNA synthesis by HIV-1 reverse transcriptase. [PDF]
It is well established that the cytosine deaminase APOBEC3G can restrict HIV-1 virions in the absence of the virion infectivity factor (Vif) by inducing genome mutagenesis through deamination of cytosine to uracil in single-stranded HIV-1 (-)DNA. However,

Reverse transcriptase inhibition: a way to defeat HIV
Human immunodeficiency virus (HIV) induces disease in humans that is known as AIDS (acquired immunodeficiency syndrome). First AIDS cases were registered in 1981, and later, types of HIV infection, such as HIV-1 and HIV-2 were identified.

Telomerase reverse transcriptase promotes angiogenesis in neonatal rats after hypoxic-ischemic brain damage [PDF]
Background Angiogenesis is an endogenous repair mechanism following hypoxic-ischemic brain damage (HIBD). Interestingly, recent studies have shown that angiogenesis can be regulated by telomerase reverse transcriptase (TERT), a critical component of ...

Cost-effectiveness of the third-agent class in treatment-naive human immunodeficiency virus-infected patients in Portugal. [PDF]
IntroductionCurrent Portuguese HIV treatment guidelines recommend initiating antiretroviral therapy with a regimen composed of two Nucleoside Reverse Transcriptase Inhibitors plus one Non-nucleoside Reverse Transcriptase Inhibitor (2NRTI+NNRTI) or two ...

Telomerase reverse transcriptase and neurodegenerative diseases
Neurodegenerative diseases (NDs) are chronic conditions that result in progressive damage to the nervous system, including Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD), and Amyotrophic lateral sclerosis (ALS).

Viral reverse transcriptases [PDF]
Reverse transcriptases (RTs) play a major role in the replication of Retroviridae, Metaviridae, Pseudoviridae, Hepadnaviridae and Caulimoviridae. RTs are enzymes that are able to synthesize DNA using RNA or DNA as templates (DNA polymerase activity), and degrade RNA when forming RNA/DNA hybrids (ribonuclease H activity).

Reverse Transcription in the Saccharomyces cerevisiae Long-Terminal Repeat Retrotransposon Ty3
Converting the single-stranded retroviral RNA into integration-competent double-stranded DNA is achieved through a multi-step process mediated by the virus-coded reverse transcriptase (RT).

HIV Rev Assembly on the Rev Response Element (RRE): A Structural Perspective
HIV-1 Rev is an ~13 kD accessory protein expressed during the early stage of virus replication. After translation, Rev enters the nucleus and binds the Rev response element (RRE), a ~350 nucleotide, highly structured element embedded in the env gene in ...
