Signaling mechanisms in genome biology: DNA repair, DNA replication and the cell cycle. Proteomic tools for exploring kinases and phosphatases.
Cornell University, Ithaca - https://smolka.wicmb.cornell.edu
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.

New preprint from the lab:

ATM controls fork processing and restart, and the PPM1D phosphatase is needed to properly balance this action of ATM.

Congratulations to @yitingcao.bsky.social @yingzhengwang.bsky.social and Jumana Badar.

Double award to the fantastic graduate student @mateuszwagner.bsky.social
I'm honored to have received the George P. Hess Award from the MBG department and the Outstanding Graduate Teaching Award from CALS. These recognitions wouldn't have been possible without the support of the incredible @smolka-lab.bsky.social and the exceptional students of BIOMG3320.

Devasting that clinical trial for Jim's PediaFlow baby heart pump is on hold due the stop on all DOD funding at Cornell.

Funded by DOD CDMRP, Congressionally Directed Medical Research Programs, yet White House stopped Congress funds

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.

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.
