ProteomicsIdentifying receptor kinase substrates using an 8,000 peptide kinase client library enriched for conserved phosphorylation sites
In eukaryotic organisms, protein kinases regulate diverse protein activities and signaling pathways through phosphorylation of specific protein substrates. Isolating and characterizing kinase substrates is vital for defining downstream signaling pathways. The Kinase Client (KiC) assay is an in vitro...

ProteomicsUnveiling orphan receptor-like kinases in plants: novel client discovery using high-confidence library predictions in the Kinase–Client (KiC) assay
Plants are remarkable in their ability to adapt to changing environments, with receptor-like kinases (RLKs) playing a pivotal role in perceiving and transmitting environmental cues into cellular responses. Despite extensive research on RLKs from the plant kingdom, the function and activity (i.e., th...

ProteomicsAnalysis of protein phosphorylation in response to the ATP treatment in Arabidopsis thaliana
The project intended to reveal protein phosphorylation patterns in Arabidopsis thaliana in response to ATP. For this purpose, Arabidopsis thaliana plants, including WT, ATP receptor mutants (p2k1, p2k2, and double mutant p2k1/p2k2), and P2K1 overexpression plants, were treated with ATP or buffer (as...

TranscriptomicsDefective cuticle-derived signals enhance extracellular ATP response and plant immunity
Extracellular ATP (eATP) acts as a damage-associated molecular pattern (DAMP) in both animals and plants. In plants, eATP is recognized by the purinergic receptors P2K1 and P2K2, which mediate responses to various environmental stresses. From a p2k1 suppressor screen, we identified two allelic mutan...

ProteomicsA receptor-like kinase pair integrates extracellular ATP and salicylic acid signaling to activate plant immunity
Extracellular ATP (eATP) is a damage-associated molecular pattern (DAMP) in both plants and animals, playing an important role as a danger signal in response to various environmental stresses. eATP works both independently and in coordination with other signaling pathways. Here, we identify a previo...
