Methylation Proteomics Service
Protein methylation is a key post-translational modification that primarily occurs on lysine and arginine residues. It regulates gene expression, chromatin structure, signal transduction, and RNA processing, and is mediated by methyltransferases using S-adenosylmethionine (SAM) as the donor. Depending on the enzyme and context, residues may undergo mono-, di-, or tri-methylation, each with distinct functional outcomes.
Abnormal methylation profiles are closely associated with cancer, neurodegeneration, immune disorders, and aging. By combining selective enrichment strategies with high-resolution mass spectrometry, MtoZ Biolabs provides Methylation Proteomics Service for global profiling and quantitative analysis of methylated proteins, delivering accurate, reproducible, and publication-ready datasets that support both basic and translational research.
