Lactylation Analysis Service
The discovery of lactylation modifications in 2019 has led to new directions for the study of the metabolite lactate's involvement in oncology, immunity, and other fields. Creative Proteomics offers high-quality acylation analysis services, including identification, quantification and characterization, providing valuable insights into your protein research.
What is Lactylation
In 2019, it was found that lactic acid accumulated during metabolism can act as a precursor substance leading to lactate modification of histone lysine and participate in the homeostatic regulation of bacterial-infected M1 macrophages, modulating inflammation, cancer, and other diseases. This broadens the way for the study of lactonization of proteins. Lactonization is one of the important post-translational modifications of proteins and may occur on any protein residue with a free amino group, such as lysine, arginine and tyrosine. In the presence of lactonase (lactoyl-CoA transferase), lactic acid is ester-bonded to the amino acid residues of the substrate protein, lactonizing it.

As a type of post-translational modification of proteins, some studies have confirmed that lactylation modification is an important way for lactic acid to exert its function, which is involved in glycolysis-related cellular functions, macrophage polarization, vascular function, mitochondria, nervous system regulation and other important life activities, and can guide new directions for research in the fields of tumors, immunity and so on.
