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,...

Protein-protein Interfaces02:04

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...
Protein Complex Assembly02:41

Protein Complex Assembly

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...
Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein.

Area of Science:

  • Sports Science
  • Molecular Biology
  • Biochemistry

Background:

  • Understanding molecular protein interactions offers health benefits for volleyball players.
  • These interactions can serve as biomarkers for metabolic status, inflammation, injury risk, and recovery.

Purpose of the Study:

  • To clarify molecular protein interactions as biomarkers for enhancing volleyball performance.
  • To identify key molecular pathways and non-coding RNAs affected by volleyball activity.

Main Methods:

  • A non-systematic review of literature from PubMed/Medline, Web of Science, Scopus, and Google Scholar.
  • Focused on biomarkers like BDNF, IGF-1, IL-6, mTORC1, and specific miRNAs (e.g., miR-223, miR-320a).

Main Results:

  • A 60-minute volleyball session elevates growth hormone and reduces IL-6, promoting an anabolic state.
  • Two weeks of training increases BDNF and IGF-1, partly due to specific miRNAs.
  • BDNF elevation varies based on genetic polymorphisms.

Conclusions:

  • Current molecular markers offer theoretical insights but lack standardization for practical application.
  • Heterogeneous study protocols and lack of reference values hinder real-time use.
  • These biomarkers are candidates for future research requiring extensive validation for personalized training monitoring.
