⭐ #NARBreakthrough! ⭐
New #cryo-EM study reveals how #transcription factor IWS1 promotes #RNApolII #elongation. Its C-terminus contains #modularmotifs that bind elongation components, stabilizing the complex. IWS1 also competes with #RECQL5 for Pol II binding.

Congratulations to Della Syau and the Farnung Lab @lucas.farnunglab.com on this outstanding work!
🚨 New preprint: GATO-seq did it again! ELOF1 is the missing promoter-proximal factor that confers RNA Pol II resistance to TFIIF. Including ELOF1, DSIF, and NELF in GATO-seq reactions recapitulates promoter-proximal pausing in vitro at physiological conditions for the 1st time.

⚡New preprint from the lab⚡: A key early checkpoint in gene expression is promoter proximal pausing of RNA polymerase II. For over 20 years, we as field have not been able to recreate pausing under realistic cellular conditions. @robertovn.bsky.social shows that ELOF1 is the missing piece.
Open q to the #cryoem crowd - what’s your fav NN/ML picker for hard SPA targets?
We use topaz with good results, but there have been a bazillion new pickers over the last years…
It is often hard to tell from the paper on each picker, as the training data matters a lot for topaz at least..
