Protein lactylation modification analysis service is a critical research solution for advancing our understanding of cellular metabolism and its role in regulating gene expression and protein function. Lactylation, a newly identified post-translational modification (PTM) derived from lactate-a by-product of glycolysis-has expanded the range of known PTMs and revealed the intricate connections between metabolic intermediates and cellular processes. Since its discovery and publication in Nature in 2019, lactylation has been shown to play key roles in immune response regulation, tumor progression, and stem cell differentiation, underscoring its broad physiological relevance.
What makes lactylation particularly significant is its direct biochemical connection to cellular metabolism. Lactylation dynamically responds to metabolic changes, providing a real-time indicator of cellular metabolic fluxes. This unique feature makes it a powerful tool for researchers studying how cells adapt to both environmental and intracellular signals.
Recognizing the growing importance of lactylation research, MtoZ Biolabs has developed a comprehensive protein lactylation modification analysis service powered by state-of-the-art mass spectrometry technologies and extensive expertise in PTM profiling. Our service is specifically designed to deliver high-resolution, quantitative, and reproducible lactylation data that meets the rigorous standards of modern molecular biology research. Whether for basic discovery or applied biomedical research, our service enables scientists to decode the functional implications of lactylation and translate their findings into real-world impact.
Mechanistic Background of Lactylation
Protein lactylation is an ester-based post-translational modification (PTM) in which a lactyl group, derived from lactate, covalently modifies lysine residues or potentially other amino acids. This modification marks a significant paradigm shift in our understanding of how metabolic intermediates influence protein function. Traditionally, metabolites were viewed as either energy substrates or signaling molecules, but lactylation demonstrates that they can also serve as direct chemical donors, altering protein activity and chromatin structure.
The establishment of lactylation is closely linked to intracellular lactate concentrations. Under conditions such as hypoxia, inflammation, or metabolic reprogramming-often seen in cancer cells-lactate accumulates within both the cytoplasm and the nucleus, providing a substrate pool for enzymatic or non-enzymatic lactylation. Histone lactylation, for instance, has been shown to enhance transcriptional activation by increasing chromatin accessibility at specific loci, which promotes gene expression.
In addition to histone lactylation, non-histone proteins are also subject to lactylation, influencing various biological processes such as enzyme catalysis, protein interactions, subcellular localization, and stability. Recent studies suggest that lactylation is a reversible modification, with specific "eraser" enzymes that can dynamically regulate its presence. This reversibility places lactylation alongside other regulatory PTMs like acetylation and methylation, which are central to cellular signaling and regulation.
Understanding lactylation at a systems level requires not only identifying the modification sites but also quantifying their abundance, dynamics, and biological context. This is where proteomics analysis of lactylation becomes indispensable. High-resolution proteomics provides the tools needed to capture lactylation across hundreds or thousands of proteins, assess their changes under various biological conditions, and integrate these findings with other omics data to enable comprehensive functional interpretation.
Applications of Lactylation Research
1. Immune System Activation and Inflammatory Signaling
Lactylation research has shown its role in modulating cytokine and chemokine expression during macrophage and T-cell activation. It regulates pro-inflammatory and anti-inflammatory responses, and may influence immune memory, tolerance, and autoimmunity, making it a potential biomarker and therapeutic target for immune-related diseases.
2. Cancer Cell Metabolism and Tumor Microenvironment Reprogramming
In cancer, lactate accumulation due to increased glycolysis enhances lactylation in oncogenic pathways, influencing tumor proliferation, angiogenesis, immune evasion, and metastasis. Lactylation research highlights its potential as a biomarker for cancer progression and a target for therapeutic interventions targeting metabolic reprogramming.
3. Stem Cell Epigenetics and Regenerative Medicine
Histone lactylation affects stem cell chromatin structure, influencing pluripotency, lineage commitment, and differentiation potential. Lactylation research opens avenues in regenerative medicine, potentially improving tissue repair and stem cell therapies.
4. Host–Pathogen Interaction and Infection Biology
Lactylation research in infection biology reveals how infections alter host metabolic pathways and reshape lactylation profiles. These changes can be used as diagnostic signatures or targeted for therapeutic interventions in infectious diseases.
5. Drug Response Profiling and Mechanism-of-Action Studies
Profiling lactylation shifts induced by drugs provides insights into drug-sensitive pathways, off-target effects, and novel drug targets. Quantitative proteomics enables precise measurement of lactylation dynamics, aiding drug development and therapeutic targeting.
Future Trends in Protein Lactylation Research
Looking forward, protein lactylation modification analysis service is set to expand into high-resolution, context-aware domains. Developments in single-cell mass spectrometry and spatial omics are enabling researchers to map PTMs at cellular and subcellular levels, providing unprecedented insight into tissue heterogeneity and disease microenvironments.
At the same time, machine learning and deep learning algorithms are redefining bioinformatics pipelines-enhancing lactylation site prediction, data classification, and cross-omics integration. These advances are poised to make lactylation a central feature in systems biology and translational medicine.
