Formylation Proteomics Service

    Post-translational modifications (PTMs) serve as critical regulators of protein function, affecting activity, stability, localization, and protein–protein interactions. Among these modifications, lysine formylation has recently emerged as a significant, yet underexplored, modification with broad implications in gene expression regulation, metabolism, aging, and disease progression. Formylation involves the covalent addition of a formyl group (-CHO) to the ε-amino group of lysine residues. This small but impactful chemical change can alter the local charge and hydrogen bonding properties of proteins, affecting their interaction with DNA, RNA, or other proteins. Formylation may compete with other lysine-targeted PTMs, such as acetylation, methylation, or ubiquitination, indicating a potential crosstalk mechanism that adds another layer of regulation to cellular signaling networks. Lysine formylation has been identified on histones, metabolic enzymes, transcription factors, and structural proteins, suggesting its involvement in chromatin remodeling, transcriptional control, and cellular stress responses. 

     

    Despite its growing biological importance, formylation remains technically challenging to study due to its low abundance, chemical lability, and lack of highly specific antibodies. Mass spectrometry (MS)-based proteomics, combined with optimized sample preparation and enrichment strategies, has become the method of choice for site-specific and quantitative analysis of formylation across biological systems.

    Analysis Workflow

    1. Sample Preparation

    Proteins are extracted, denatured, reduced, alkylated, and enzymatically digested into peptides.

     

    2. Formylated Peptide Enrichment

    Enrichment is performed using anti-formyllysine antibodies or optimized chemical strategies to isolate modified peptides.

     

    3. LC-MS/MS Analysis

    Enriched peptides are analyzed using high-resolution mass spectrometry for accurate identification and site localization.

     

    4. Data Processing

    Raw data are processed to identify formylated peptides, localize modification sites, and quantify differences across samples.

     

    5. Bioinformatics Interpretation

    Identified formylation events are mapped to pathways, biological processes, and potential crosstalk with other PTMs.

    Case Study

    Formylated Peptides as Inflammatory Drivers in ARDS

    A study identified elevated levels of mitochondrial formylated peptides in the bronchoalveolar lavage fluid and serum of patients with acute respiratory distress syndrome (ARDS) using LC-MS/MS. These peptides were shown to activate neutrophils and promote chemotaxis via formyl peptide receptor 1 (FPR1). In mouse models of sterile lung injury, both genetic deletion and pharmacological inhibition of FPR1 attenuated inflammation. This research highlights the biological relevance of formylated peptides in inflammatory lung disease and underscores the utility of mass spectrometry-based formylation analysis in uncovering disease-associated PTM mechanisms.
