It is interesting that the different specificities of sponge proteins to signaling molecules may explain different mechanisms in the phage-bacteria arms race.

Interesting, but how does it know which gene is the mutated one when the two alleles are different? Dose this happen for only deleterious mutations, or also happen for beneficial ones

One of the main stories of my postdoc is finally out! It builds on an intuition from my early days in omics data analysis: our signaling pathways are simply too small, underrepresenting cellular complexity after stimulation. Something obvious, yet surprisingly hard to quantify.

When I first learned about omics at university, I confidently stopped caring about single proteins. Fast-forward 4 years of a system’s biology PhD, I now have the most amazing favorite single protein which I can’t stop thinking about. Here is the story of how that happened 👀

A Very comprehensive study! Some previous studies have used drug-induced changes in target abundance to identify targets; although it’s not always the case.
