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 proteomics...

Main Methods:

  • Proteomics for comprehensive protein identification and quantification.
  • Peptidomics for analyzing bioactive peptides derived from milk proteins.
  • Bioinformatics for predicting protein functions and nutraceutical potential.

Main Results:

  • Characterization of species-specific milk protein composition and micelle structures.
  • Identification of various post-translational modifications (PTMs) in milk proteins.
  • Prediction of latent nutraceutical properties based on protein sequences and bioactive peptides.

Conclusions:

  • Proteomics, peptidomics, and bioinformatics offer powerful tools for understanding milk protein functionality.
