ok, Genome Stability people. Here are our two starter packs - since I can't pin them both independently to my profile, have to make a new post. Still adding new people to the second pack. As usual, please reach out if you would like to be added!

Check out our new biosensor technology to study DDR kinase signaling: ProKAS.

We combine:
-proteomics
-engineered peptide sensors
-a new concept of amino acid barcodes

ProKAS tracks kinase signaling with spatial resolution and produces highly quantitative data.

Our paper in Science is out! @souravagrawal.bsky.social, @rlynn.bsky.social, @susvirkar.bsky.social, and the rest of the team show human RPA is a telomerase processivity factor essential for telomere maintenance. This reshapes our thinking about telomerase regulation. www.science.org/doi/10.1126/...
Human RPA is an essential telomerase processivity factor for maintaining telomeres
Telomerase counteracts telomere shortening by repeatedly adding DNA repeats to chromosome ends. We identified the replication protein A (RPA) heterotrimer as a telomerase processivity factor critical ...

We carried an agarose/EtBr gel to the imager on a plastic box cover that was labeled with red sharpie. The gel acquired a nice but unexpected label. How did this happen? The box was not imaged. Sharpies don't get washed off that easily. What kind of sorcery is this?
The label says "biotin HA 6/6"
