Dataset Summary
TitleS-acylation and fatty acylation in Naïve and LPS/IFN- gamma activated Raw264.7
DescriptionThe advances in chemical proteomics have significantly expanded our understanding of the diversity and abundance of fatty-acylated proteins in eukaryotes, and reveal novel functions for these lipid protein modifications. Nonetheless, quantitative comparative proteomic analysis of fatty-acylated proteins in different cellular states is still challenging. To address these limitations, we systematically evaluated different proteomic methods (alk-16 chemical reporter and acyl-RAC) and established robust conditions to selectively and quantitatively profile fatty-acylated proteins in mammalian cells. Using a combination of metabolic labeling with fatty acid chemical reporters, selective chemical enrichment and label-free proteomics, we performed a quantitative analysis of fatty-acylated proteins in naïve and activated macrophages. These studies revealed novel fatty-acylated proteins associated with host immunity that are differently expressed and lipid-modified in different cellular states.
