G-quadruplexes as novel cis-elements controlling transcription during embryonic development
(Oxford University Press, 2016-05)
G-quadruplexes are dynamic structures folded in G-rich single-stranded DNA regions. These structures have been recognized as a potential nucleic acid based mechanism for regulating multiple cellular processes such as ...
Transcriptional control by G-quadruplexes: In vivo roles and perspectives for specific intervention
(Taylor & Francis, 2017-01)
G-quadruplexes are non-canonical DNA secondary structures involved in several genomic and molecular processes. Here, we summarize the main G-quadruplex features and evidences proving the in vivo role on the transcriptional ...

Chaperones and their role in telomerase ribonucleoprotein biogenesis and telomere maintenance
(2019-01-01)
Telomere length maintenance is important for genome stability and cell division. In most eukaryotes, telomeres are maintained by the telomerase ribonucleoprotein (RNP) complex, minimally composed of the Telomerase Reverse ...
CNBP controls transcription by unfolding DNA G-quadruplex structures

Crystal structure, DNA binding studies, nucleolytic property and topoisomerase I inhibition of zinc complex with 1,10-phenanthroline and 3-methyl-picolinic acid
(Springer, 2010-02-01)
Crystal structure analysis of the zinc complex establishes it as a distorted octahedral complex, bis(3-methylpicolinato-kappa(2) N,O)(2)(1,10-phenanthroline-kappa(2) N,N)-zinc(II) pentahydrate, [Zn(3-Me-pic)(2)(phen)]center ...

A multi-approach analysis highlights the relevance of RPA-1 as a telomere end-binding protein (TEBP) in Leishmania amazonensis
(2020-07-01)
Background: Telomeres are chromosome end structures important in the maintenance of genome homeostasis. They are replenished by the action of telomerase and associated proteins, such as the OB (oligonucleotide/oligosacch ...
Venomics of the Central American Lyre snake Trimorphodon quadruplex (Colubridae: Smith, 1941) from Costa Rica
(2020)
Rear-fanged colubrid snakes include hundreds of species globally that possess a Duvernoy's venom gland and often one-several enlarged rear maxillary teeth. We investigated the venom proteome of the Central American Lyre ...
