Defining the human gallbladder proteome by transcriptomics and

Proteomics is a modern discipline concerned with applying different techniques of molecular biology, biochemistry, and genetics to elucidate the structure, function, and interactions of the proteins produced by the genes of a particular cell, tissue, or organism. Affinity-based proteomics offers opportunities for the discovery and validation of disease-associated proteins in human body fluids. This thesis describes the use of antibody-based immunoassays for multiplexed analysis of proteins in human plasma, serum and cerebrospinal fluid (CSF). For this, we applied affinity proteomics, utilizing tandem affinity purifications combined with mass spectrometry. Analysis of the acquired proteomics data provides evidence that ADGRs not only have functional roles at synapses but also at intracellular membranes, namely at the endoplasmic reticulum, the Golgi apparatus, mitochondria, and mitochondria‐associated membranes (MAMs).

Here, we synthesize and characterize a photoreactive GTP affinity probe that covalently photocross-links to protein targets and has an alkyne handle for click chemistry conjugation to reporter tags. Affinity proteomics seeks to use them to analyse proteomes using collections of specific binding reagents. While the most familiar affinity reagents are the classical antibodies and their fragments, there are also alternative engineered forms of novel protein scaffolds and nucleic acid aptamers with similar diversity and binding properties. Sacco et al. found that the affinity proteomics data identified a number of protein interactors that co-enriched with the phosphatase enzymes under examination, with around 10% of the data reported elsewhere in research literature. Their new affinity proteomics approach also identified new phosphatase interactions such as DLC1 and ATM. Proteomics is the analysis of the entire protein complement of a cell, tissue, organism, or species. The application of technologies to identify and quantify proteins is crucial in early disease diagnosis, prognosis, and drug development.

The approach is based on affinity reagents raised toward bioinformatics-designed protein epitope signature tags corresponding to unique regions of individual gene loci.

Affinity pull-downs are one of the most common types of proteomic experiments performed in any research laboratory. Combining such experiments with mass spectrometry can be challenging; but it is a very powerful approach when studying protein-protein interactions.

Large-Scale Screening of Preferred Interactions of Human Src

Affinity Proteomics Within Affinity Proteomics Group we develop, design and apply recombinant antibody microarrays for high-throughput (disease) proteomics, with a particular focus on oncoproteomics and autoimmunity (1-3). Here we show that an affinity proteomics strategy using affinity-purified antibodies raised against recombinant human protein fragments can be used for chromosome-wide protein profiling.
