Abstract:

Protein phosphorylation plays an important role in various life processes, such as signaling, metabolism, and growth. In addition to the well-known O-phosphorylation, which occurs on serine, threonine and tyrosine side chains, N-phosphorylation, occurring on histidine, arginine and lysine side chains, has attracted much attention. However, due to the chemical instability of N-phosphorylation, the studies on it are still in the nascent stage. In this review, enrichment and detection methods for protein N-phosphorylation are reviewed, and future research in this field is prospected.

Key words: protein N-phosphorylation, enrichment, detection, review
