Analysis of protein lysine acetylation in vitro and in vivo

Protein lysine acetylation, referring to acetylation of the epsilon-amino group of a lysine residue, has recently emerged as an important post-translational modification for regulating protein functions in various organisms. Like phosphorylation, lysine acetylation is a rapidly reversible and precisely controlled covalent modification that serves as a simple on/off switch or participates in a codified manner with other post-translational modifications to regulate protein functions in different cellular and developmental processes. This unit describes and discusses methods used for in vitro and in vivo determination of lysine acetylation.
