The SAMHD1-mediated block of LINE-1 retroelements is regulated by phosphorylation

open access: yesMobile DNA, 2018
Background The restriction factor SAMHD1 regulates intracellular nucleotide level by degrading dNTPs and blocks the replication of retroviruses and DNA viruses in non-cycling cells, like macrophages or dendritic cells. In patients, inactivating mutations

Cytological features of penaut genome [PDF]

open access: yes, 2017
The genus Arachis is composed of 82 species (Krapovickas and Gregory 1994; Valls and Simpson 2005; Valls et al 2013; Santana and Valls 2015) mainly distributed within a large region of South America, which extends from the eastern foothills of the Andes ...

Generalized nuclear localization of retroelement transcripts

open access: yesMobile DNA, 2022
Abstract Background LINE-1s, Alus and SVAs are the only retrotransposition competent elements in humans. Their mobilization followed by insertional mutagenesis is often linked to disease. Apart from these rare integration events, accumulation of retrotransposition intermediates in the cytoplasm is potentially pathogenic ...

Retroelement origins of pre‐mRNA splicing [PDF]

open access: yesWIREs RNA, 2020
AbstractRecent cryo‐EM structures of a group II intron caught in the process of invading DNA have given new insight into the mechanisms of both splicing and retrotransposition. Conformational dynamics involving the branch‐site helix domain VI are responsible for substrate exchange between the two steps of splicing.

Differential Methylation of Syncytin-1 and 2 Distinguishes Fetal Growth Restriction from Physiologic Small for Gestational Age

open access: yesAmerican Journal of Perinatology Reports, 2018
Objective The retroviral genes encoding Syncytin-1 (SYN1) and Syncytin-2 (SYN2) are epigenetically regulated, uniquely expressed in the placenta and critical to placental function.

Telomeres in Evolution and Development from Biosemiotic Perspective [PDF]

open access: yes, 2007
Telomeres identify natural chromosome ends being different from broken DNA through differences in their "molecular syntax" (M.Eigen) which determines the functions of reverse transcriptase and its integrated RNA template, telomerase.

COVID-19, Retroelements, and Aging [PDF]

open access: yesAdvances in Gerontology, 2021
The review presents an analysis of the scientific data on the characteristics of COVID-19 from the perspective of potential interactions between the virus and the host genome retroelements. According to global statistical data, severe COVID-19 with immune-system hyperactivity is observed mainly in elderly people.

Retrotransposon-Encoded Reverse Transcriptase in the Genesis, Progression and Cellular Plasticity of Human Cancer [PDF]

open access: yes, 2011
LINE-1 (Long Interspersed Nuclear Elements) and HERVs (Human Endogenous Retroviruses) are two families of autonomously replicating retrotransposons that together account for about 28% of the human genome.

Efficient retroelement-mediated DNA writing in bacteria [PDF]

open access: yesCell Systems, 2020
AbstractThe ability to efficiently and dynamically change information stored in genomes would enable powerful strategies for studying cell biology and controlling cellular phenotypes. Current recombineering-mediated DNA writing platforms in bacteria are limited to specific laboratory conditions, often suffer from suboptimal editing efficiencies, and ...
