Ribosomal Targeted Proteomic Analysis Services
Are you struggling to identify new drug targets or understand complex disease mechanisms in translational research? Our ribosomal-targeted proteomic analysis services help you accelerate drug discovery and deepen your understanding of cellular processes by providing unparalleled insights into the dynamic world of protein synthesis through advanced mass spectrometry techniques.
Background
Ribosomal-targeted proteomic analysis focuses on the comprehensive study of ribosomal proteins (RPs) and their associated factors, which are critical components of the cellular protein synthesis machinery. This advanced proteomic approach delves beyond global protein expression to specifically examine the ribosome's dynamic composition, post-translational modifications (PTMs), and interactions. Recent research highlights the ribosome not merely as a passive translation machine but as an active regulator of gene expression, with variations in RP composition linked to developmental stages, cell types, and pathophysiological contexts, including ribosomopathies and cancer. By directly analyzing the ribosomal proteome, we gain unparalleled insight into the translational control mechanisms that drive cellular function and disease.

Core Procedures
-
Sample Preparation and Ribosome Isolation
This crucial initial step involves the gentle lysis of cells or tissues, followed by sophisticated differential centrifugation or affinity purification techniques to isolate intact ribosomes and their associated proteins. The outcome is a high-purity ribosomal fraction optimized for subsequent analysis. -
Protein Digestion and Peptide Generation
The isolated RPs are then subjected to enzymatic digestion to break them down into smaller, manageable peptides. This step is critical for mass spectrometry compatibility, ensuring optimal signal detection.
-
Advanced Mass Spectrometry Analysis
Utilizing state-of-the-art high-precision mass spectrometry platforms, we perform in-depth analysis of the generated peptides. This includes both qualitative identification and accurate quantitative measurement of RPs and their modifications. Our diverse data acquisition modes, including DIA, DDA, and PRM, ensure comprehensive coverage and reliable data reproducibility.
-
Proteomics Bioinformatics Analysis
Raw mass spectrometry data undergoes rigorous bioinformatics processing. This involves data quality control, protein identification, quantitative analysis, differential protein statistical analysis, and functional annotation, such as GO/KEGG/COG enrichment analysis. This step extracts meaningful biological insights from complex datasets.

FAQs
Q: How does ribosomal targeted proteomic analysis differ from standard proteomics services?
A: While standard proteomics offers a broad overview of the entire cellular proteome, ribosomal targeted proteomic analysis specifically focuses on the ribosome and its associated proteins. This targeted approach offers significantly higher sensitivity and specificity for this critical cellular machinery, allowing for the detection of subtle changes in ribosomal composition, modifications, and interactions that might be missed in a global analysis. This depth provides more direct insights into translational regulation and its role in specific biological contexts.
Q: What types of biological questions can your ribosomal targeted proteomic analysis services help answer?
A: Our services are ideally suited for investigating questions related to translational control, ribosome heterogeneity, disease mechanisms involving protein synthesis dysregulation, and the identification of novel drug targets or biomarkers within the ribosomal machinery. If your research involves understanding how protein production is regulated or how ribosomal dysfunction contributes to disease, our services can provide crucial insights.
Q: What is the typical sample requirement for this service, and how should samples be prepared?
A: We are flexible with sample types, including cell pellets, fresh or frozen tissue samples, and even pre-isolated protein or RNA fractions. For optimal results, we recommend discussing your specific sample type and quantity with our specialists during the consultation phase. Generally, samples should be flash-frozen or stored appropriately to preserve protein integrity. Our team will provide detailed guidelines for shipping and handling.
Q: Can your service identify PTMs on RPs?
A: Absolutely. A key strength of our ribosomal targeted proteomic analysis services is our ability to identify and quantify various PTMs on RPs, such as phosphorylation, acetylation, and methylation. These modifications are crucial for understanding the dynamic regulation of ribosomal function and their role in cellular signaling and disease.
