Mass Spectrometry-Based Analysis of TRPP2 Phosphorylation

Methods Mol Biol. 2019:1987:51-64. doi: 10.1007/978-1-4939-9446-5_4.


Differential phosphorylation of proteins is a key regulatory mechanism in biology. Immunoprecipitation-coupled mass spectrometry facilitates the targeted analysis of transient receptor ion potential channel polycystin-2 (TRPP2) phosphorylation. However, empirical testing is required to optimize experimental conditions for immunoprecipitation and mass spectrometry. Here, we present a detailed workflow for the reliable analysis of endogenous TRPP2 phosphorylation in differentiated renal epithelial cells.
