Abstract

Myristoylation is a type of lipidation with important functions. Owing to the lack of high-quality antibodies against myristoylation, developing alternative methods for profiling myristoylated proteins is important. Here, we provide a protocol for metabolic labeling using click chemistry to profile myristoylated proteins in C. elegans. Our approach improves the signal/noise ratio by covalently linking the myristoylated proteins to the beads. This protocol provides a highly specific and reproducible way for enriching myristoylated proteins, which could be modified to analyze other types of lipidations. For complete details on the use and execution of this protocol, please refer to Tang et al. (2021).
