MULTIPROTEIN COMPLEXES Meaning and
Definition
-
Multiprotein complexes refer to large and intricate assemblies consisting of multiple protein molecules that come together to perform specific biological functions. These complexes are essential for various cellular processes such as gene expression, signal transduction, cell signaling, and metabolism.
In multiprotein complexes, individual proteins interact and bind to each other through non-covalent interactions, forming stable structures with defined 3D shapes. The interaction between the proteins within the complex is highly specific and often mediated by intricate networks of weak interactions including hydrogen bonding, electrostatic interactions, hydrophobic interactions, and van der Waals forces.
Multiprotein complexes are characterized by their size, composition, and organization. They can range from simple dimers composed of two proteins to large macromolecular complexes with dozens or even hundreds of proteins. The arrangement and stoichiometry of the proteins within the complex are vital for its proper functioning.
These complexes often exhibit allosteric regulation, meaning that the binding of a ligand or substrate to one protein within the complex can affect the conformation and function of other proteins within the assembly. This allows for highly regulated and coordinated cellular processes.
Multiprotein complexes play crucial roles in various biological processes, including DNA replication and repair, protein synthesis, cell cycle control, cell signaling, and immune response. Understanding the structure, organization, and dynamics of these complexes is essential for unraveling the complex network of cellular pathways and for the development of therapeutic interventions targeting specific protein-protein interactions within these assemblies.

Etymology of MULTIPROTEIN COMPLEXES
The etymology of the word "multiprotein complexes" can be broken down as follows:
1. Multi-: The prefix "multi-" comes from the Latin word "multus" meaning "many" or "much". It is used to indicate multiple or many.
2. Protein: The word "protein" comes from the French word "protéine" (from the Greek word "prōteios") meaning "primary" or "first quality". It was initially used to describe a class of nitrogenous organic compounds found in living organisms that play crucial roles in various biological functions.
3. Complexes: The term "complexes" comes from the Latin word "complexus" meaning "entwined" or "twisted together". In the context of biology, it refers to molecular structures that consist of multiple components bound together.
Therefore, "multiprotein complexes" can be understood as molecular structures consisting of multiple protein components.
