Protein phosphorylation, recognised as the most prevalent and critical form of post-translational modification, functions as a central regulatory hub for cellular life activities by governing cell growth, proliferation, metabolism, physiological regulation, and signal transduction. Activated phosphorylated proteins and phosphorylated molecular species typically initiate cascades of biochemical reactions and protein interactions that drive cellular activation, motility, proliferation, and metabolic reprogramming. Therefore, the accurate and precise quantification of phosphorylated proteins at the cellular level is essential for deciphering the molecular mechanisms underlying cellular functionality.
