Potential Rad54 separation of function mutation highlights unique roles during homologous recombination
Author summary Homologous recombination (HR) is a DNA double-strand break repair pathway that functions at DNA breaks and stalled or collapsed replication forks. Rad51 is a critical enzyme that mediat...

Today we are very pleased to share our latest article available now online @narjournal.bsky.social about the role of Slx4 scaffold and Fun30 (SMARCAD1 homolog) in DNA damage response regulation and replication fork protection against Top1-DNA crosslinks. academic.oup.com/nar/article/...
- Checkpoint signaling slows down replication in response to Top1 poisoning by camptothecin. 
- Checkpoint signaling is actively dampened by Slx4 and Fun30 to permit Exo1-dependent resection of replication forks. 
- Checkpoint dampening is critical to promote replication fork protection and preserve genome stability.

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. Just published today: rdcu.be/ePNo0

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. www.biorxiv.org/content/10.1...
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.
