Fatty-acyl conjugated amino-hexyl agarose pulldown with HeLa SILAC whole cell extract

ABSTRACT: C10:0 and C14:0 fatty acids were conjugated onto agarose beads, and used for pull-down with stable isotope (light: K0R0, heavy: K8R10) labeled Hela whole cell extract. C2:0 conjugated beads were used as control. Both forward (C2:0-light, C10:0 or C14:0-heavy) and reverse (C2:0-heavy, C10:0 or C14:0-light) labeling and pull-down experiments were performed.

Covalent post-translational modification (PTM) of proteins with acyl groups of various carbon chain-lengths regulates diverse biological processes ranging from chromatin dynamics to subcellular localization. While the YEATS domain has been found to be a prominent reader of acetylation and other short acyl modifications, whether additional acyl-lysine reader domains exist, particularly for longer carbon chains, is unclear. Here, we employed a quantitative proteomic approach using various modified  ...[more]
