- Understanding direct substrates is crucial for elucidating kinase roles in signaling pathways.
Purpose of the Study:
- To present a large-scale phosphoproteomics method for characterizing plant receptor-like kinases.
- To identify direct substrates and understand the functional roles of these kinases within signaling networks.
Main Methods:
- Development of a label-free quantitation-based comparative phosphopeptide profiling method.
- Application of the method to knockout mutants of receptor-like kinases.
- Integration with physiological and cell biological experiments.
Main Results:
- The study established a novel phosphoproteomics approach for plant kinase research.

21.2K
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

19.6K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...
