Targeted proteomics analyses of phosphorylation-dependent signalling networks

Area of Science:

• Molecular Biology
• Cell Signaling
• Proteomics

Background:

• Protein phosphorylation is a key regulatory mechanism in cellular signaling networks.
• Kinases and phosphatases tightly control phosphorylation, influencing dynamic network architecture.
• Understanding dynamic signaling networks is crucial for cell biology in health and disease.

Purpose of the Study:

• To review the contribution of targeted proteomics to understanding phosphorylation-dependent protein interaction networks.
• To explore the application of these proteomics approaches in addressing clinical problems.

Main Methods:

• Utilizes established targeted proteomics techniques: Selected Reaction Monitoring (SRM).
• Incorporates advanced methods: Parallel Reaction Monitoring (PRM) and Data-Independent Acquisition (DIA).
• Focuses on delineating temporal quantitative profiles of protein interaction networks.

Main Results:

• Targeted proteomics has significantly advanced the comprehension of phosphorylation-dependent signaling networks.
