The crotonylation of a lysine residue in a protein. Crotonyl is the univalent radical CH3-CH=CH-CO- derived from crotonic acid. [PMID:25818647, Wikipedia:crotonyl]
Peptidyl-lysine crotonylation is a post-translational modification (PTM) that involves the covalent attachment of a crotonyl group (CH3CH=CHCO) to the ε-amino group of lysine residues in proteins. This modification is catalyzed by a family of enzymes known as crotonyltransferases.
Crotonylation is a dynamic process that can be regulated by various factors, including cellular stress, nutrient availability, and developmental stage. The process begins with the transfer of a crotonyl group from a donor molecule, such as crotonyl-CoA, to the ε-amino group of lysine. This reaction is catalyzed by crotonyltransferases, which have distinct substrate specificities and are often involved in specific cellular pathways.
Crotonylation can significantly alter the structure and function of proteins by affecting their interactions with other molecules, their stability, and their catalytic activity. It has been linked to a wide range of cellular processes, including gene regulation, signal transduction, and metabolism.
The biological significance of crotonylation is still being actively explored, but studies suggest that it plays a crucial role in maintaining cellular homeostasis and responding to various environmental cues. For example, crotonylation has been shown to regulate the activity of histone proteins, which are involved in DNA packaging and gene expression. It has also been implicated in the regulation of metabolic enzymes and the control of inflammation.
Furthermore, dysregulation of crotonylation has been associated with several disease states, including cancer and neurodegenerative disorders. This highlights the importance of understanding the mechanisms underlying crotonylation and its potential therapeutic implications.'
