Quantitative Proteomic Analysis of Protein Complexes CONCURRENT IDENTIFICATION OF INTERACTORS AND THEIR STATE OF PHOSPHORYLATION*□S

Protein complexes have largely been studied by immunoaffinity purification and (mass spectrometric) analysis. Although this approach has been widely and successfully used it is limited because it has difficulties reliably discriminating true from false protein complex components, identifying post-translational modifications, and detecting quantitative changes in complex composition or state of ...

Quantitative proteomic analysis of protein complexes: concurrent identification of interactors and their state of phosphorylation.

Protein complexes have largely been studied by immunoaffinity purification and (mass spectrometric) analysis. Although this approach has been widely and successfully used it is limited because it has difficulties reliably discriminating true from false protein complex components, identifying post-translational modifications, and detecting quantitative changes in complex composition or state of ...

A proteomic analysis of arginine-methylated protein complexes.

Arginine methylation is a post-translational modification that results in the formation of asymmetrical and symmetrical dimethylated arginines (a- and sDMA). This modification is catalyzed by type I and II protein-arginine methyltransferases (PRMT), respectively. The two major enzymes PRMT1 (type I) and PRMT5 (type II) preferentially methylate arginines located in RG-rich clusters. Arginine met...

A proteomic strategy for global analysis of plant protein complexes.

Global analyses of protein complex assembly, composition, and location are needed to fully understand how cells coordinate diverse metabolic, mechanical, and developmental activities. The most common methods for proteome-wide analysis of protein complexes rely on affinity purification-mass spectrometry or yeast two-hybrid approaches. These methods are time consuming and are not suitable for man...
