Researchers examine circRNAs encoded by MERS-CoV, SARS-CoV-1 and SARS-CoV-2

New research published in Briefings in Bioinformaticsm has identified thousands of circRNAs in Betacoronaviruses, including MERS-CoV, SARS-CoV-1, and SARS-CoV-2, from the RNA-sequencing data of viral infections. These coronaviruses have a similar genomic structure with a diverse circRNA coding ability. Researchers have also systematically characterized circRNAs in coronaviruses, with regard to their size, sequence feature, expressions, genome, location preference, and functions. This opens the door to further explore and understand the mode of action of individual circRNAs in coronaviruses.

Research finds polymerase of SARS-CoV-2 can adopt an alternative structure

New research by German scientists has uncovered another form of coronavirus polymerase. The current polymerase thought to be used for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a viral RNA-dependent RNA polymerase (RdRp) for replication and transcription. It contains a monomeric enzyme with the catalytic subunit nsp12, two copies of subunit nsp8, and one copy of subunit nsp7.

Researchers examine SARS-CoV-2 RNA interactome

A new study focuses on the identification of RNA-binding protein by mass spectrometry (ChIRP-M/S) approach. This study develops a global map that contains the complete set of host proteins that involve the SARS-CoV-2 genome during infection. This study has successfully identified new SARS-CoV-2 host dependency factors by merging proteomics data with gene silencing experiments. Such a discovery has paved new roads to develop more antiviral therapies.

Study finds rapid spread of B.1.1.220 variant with E484K mutation in New York

New research led by Patrick McGann from Walter Reed Army Institute of Research found the first cases of the B.1.1.220 variant with an E484K mutation on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein. Their results suggest the variant recently emerged as B.1.1.220 was not found in New York before December 2020. Still, it quickly made up 25% of coronavirus strains in late January and early February.
