Proteomics01:33

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...
Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

  • To guide researchers in selecting appropriate methods based on sample complexity and experimental aims.

Main Methods:

  • Distillation of diverse proteomic approaches into a core set of techniques.
  • Analysis of the relationship between sample complexity and analytical challenges.
  • Contrast of current, broadly applicable proteomics with areas needing further development.

Main Results:

  • Identification of a "canon" of techniques tailored for specific biological questions.
  • Differentiation between mature, widely usable proteomic applications and those requiring advanced expertise.
  • Framework for assessing the feasibility and resource requirements of proteomic experiments.

Conclusions:

  • Proteomic strategy selection is critical and depends on the biological question and sample complexity.
