Last day repping @smolka-lab.bsky.social with @wjcomstock.bsky.social at the 73nd(?) #ASMS2025! Had an awesome time—already excited for next year!

Big thanks to everyone in the @smolka-lab.bsky.social for their support on this project! 🙏

My first-author paper on uncovering a non-canonical Tel1 motif using phosphoproteomics has been published in JBC! Amazing to work with @rainshj.bsky.social using both untargeted and targeted mass spectrometry. Check it out:

Excited to share our preprint reporting a completely new approach to study kinase signaling: ProKAS.

ProKAS is based on a tandem array of peptide sensors with barcodes for multiplexed, spatial and kinetic applications.

We applied it to DDR kinases. Please share.

We developed a proteomic kinase activity sensor platform (ProKAS) for the analysis of kinase signaling using mass spectrometry. ProKAS is based on a tandem array of peptide sensors with amino acid barcodes that allow multiplexed analysis for spatial, kinetic, and screening applications.

In this new paper we find that Tel1 kinase (yeast ATM) targets D/E-S/T motifs… more prevalent than S/T-Q!

Mec1 (yeast ATR) can’t target D/E-S/T, so we think D/E-S/T targeting allows Tel1 functional specialization.

A mutation in Tel1 makes it only target S/T-Q… and cells become CPT sensitive.
