RNA binding as an emerging regulatory dimension in the type I IFN response dlvr.it/TRr3sF

RNA binding as an emerging regulatory dimension in the type I IFN response

Iselin et al. explore how the type I IFN response regulates RNA-binding activity using RNA-interactome capture and extend the RIC protocol to assess the role of phosphorylation in this process....

We asked the question do solid particles have a role to play in the separation space within modern proteomics? Would these very small particles in short columns for fast gradients be a good idea for modern fast and sensitive MS? The answer was not no! pubs.acs.org/doi/10.1021/acs…

Are Solid Particles Ready for Prime-Time Proteomics?

We evaluate the performance of nonporous C-18 stationary phases in high-speed proteomics workflows. We employed two commercially available sub-2 μm nonporous particle (NPP) materials, ODS-IIIE (1.5...

🚨 New paper in @PLOSPathogens! 🚨 Together with @brennanlab, we mapped – for the first time – how tick RNA-binding proteins rewire during virus infection. 283 proteins changed activity, revealing key players in viral fitness. Read here: doi.org/10.1371/journal.ppat…

Uukuniemi virus infection causes a pervasive remodelling of the RNA-binding proteome in tick cells

Author summary In host cells, RNA-binding proteins play essential roles in the life cycle of many viruses by influencing how viral RNA is processed, translated, replicated and assembled into virions....

We were just using NHS chemistry for some protein conjugation when we noticed some odd prominent side products. It turns out thio-nhs reagents (a major class of reagents) has some notable side reactions that happen all the time. nature.com/articles/s41467-0…

Thio-NHS esters are non-innocent protein acylating reagents

Nature Communications - N-Hydroxysuccinimide (NHS)-ester derivatives are one of the most widely used acylating agents. In this work, the authors report that ring-opening reaction of the succinimide...

🚨🚨News: Interested in the proteome configuration that makes a cell permissive or hostile to virus infection? Why mRNA levels do not fully reflect the proteome status after interferon treatment? See the new paper from @castello_lab and Mohammed lab mcponline.org/article/S1535-…
