Exciting times for protein science! 🧪
We've seen tools for editing DNA and RNA - now we can do it with proteins too! Intein pairs can act like transposons within protein sequences.

New preprint on how a minimal Salmonella kinase needs a host kinase to activate it. Work led by @timeshpillay.bsky.social and another great collaboration with @katrinrittinger.bsky.social @crick.ac.uk biorxiv.org/content/10.1...
Salmonella effector kinase SteC is activated by host-mediated phosphorylation
The pathogen Salmonella , which causes significant human morbidity and mortality, encodes an effector kinase, SteC, which mediates actin polymerisation and cell migration. Given the minimal nature of ...

We need to have a ‘code of conduct’ for reviewing manuscripts, like (1) if you say that something is not novel then provide the reference. (2) If you propose an experiment, state precisely to which claim it is crucial. (3) If you want to say something nasty then sign your name.
