Bio-Protocol, 2014 Helicases are a class of enzymes which are motor proteins using energy derived from ATP hydrolysis to move directionally along a nucliec acid phosphodiester backbone (such as DNA, RNA and DNA-RNA hybrids) and separate two annealed nucleic acid strands ...

Molecular Oncology, EarlyView.Analysis of treatment‐naïve high‐grade serous ovarian carcinoma (HGSOC) and control tissues for ERVs, LINE‐1 (L1), inflammation, and immune checkpoints identified five clusters with diverse patient recurrence‐free survivals. An inflammation score was calculated and correlated with retroelement expression, where one novel cluster (Triple‐I) with high ...

PLoS Pathogens, 2019 Positive-stranded RNA viruses replicate inside cells and depend on many co-opted cellular factors to complete their infection cycles. To combat viruses, the hosts use conserved restriction factors, such as DEAD-box RNA helicases, which can function as ...

mBio, 2018 Present in every kingdom of life, generally in multiple copies, DEAD-box RNA helicases are specialized enzymes that unwind RNA secondary structures. They play major roles in mRNA decay, ribosome biogenesis, and adaptation to cold temperatures.

Possible role of human ribonuclease dicer in the regulation of R loops
FEBS Open Bio, EarlyView.R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Oxysterol binding protein (OSBP) contributes to hepatitis E virus replication
Virology JournalHepatitis E virus (HEV) is a positive-sense, single-stranded RNA virus and causes primarily acute self-limiting infections. The ORF1 of the HEV genome encodes a polyprotein around 190 kDa, which contains several putative domains, including helicase and ...

Cloning and characterisation of the S.pombe rad15 gene, a homologue to the S.cerevisiae RAD3 and human ERCC2 genes [PDF]
, 1992 The RAD3 gene of Saccharomyces cerevisiae encodes an ATP-dependent 5' - 3' DNA helicase, which is involved in excision repair of ultraviolet radiation damage.

Arginine Methylation of RNA Helicase A Determines Its Subcellular Localization*
Journal of Biological Chemistry, 2004 RNA helicase A (RHA) undergoes nuclear translocation via a classical import mechanism utilizing karyopherin beta. The nuclear transport domain (NTD) of RHA is known to be necessary and sufficient for its bi-directional nuclear trafficking. We report here

Liver‐specific lncRNAs associated with liver cancers
FEBS Open Bio, EarlyView.Long non‐coding RNAs (lncRNAs) are regulatory molecules with various functions. They are more tissue‐specific than proteins and can be used as potential biomarkers, particularly in cancer diagnostics and prognosis. In this review, we have systematically compiled all lncRNAs with exclusive expression in the human liver, verified their liver specificity ...
