Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Protein and Protein Structure

Protein and Protein Structure

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

Area of Science:

Structural Biology
Computational Biology
Biophysics

Background:

Understanding protein structure variations is crucial for revealing biological effects.
Existing methods struggle to accurately measure and locate subtle protein structure changes.

Purpose of the Study:

To develop a systematic and high-throughput method for measuring and locating protein structural alterations.
To identify structural changes induced by subtle variations that are missed by current techniques.

Main Methods:

Developed MELO (measurement based on residues' geometric characteristics & relative distance and location based on secondary structure variation & protein segment shift).
Employed geometric characteristics, relative distances, secondary structure variation, and protein segment shifts for analysis.

Main Results:

MELO effectively captures protein structure changes of varying magnitudes (>30% increase observed).
The method precisely locates regions of alteration in critical case studies.
Identified over 10,000 novel structural changes missed by existing methods.
An online server is available for structure comparison and data download.

Conclusions:

MELO provides a robust approach for detecting and localizing subtle protein structural variations.
The findings enhance the understanding of how minor changes impact protein structure and function.
The publicly available data and server facilitate further research in structural biology.
