Summary
Cyclophilins are essential immunophilins with peptidyl-prolyl cis-trans isomerase activity found across all life. Beyond immunosuppression, they play crucial roles in cell signaling, protein folding, and human diseases.
Area of Science:
- Biochemistry
- Molecular Biology
- Immunology
Background:
- Cyclophilins are a class of proteins known as immunophilins.
- They possess peptidyl-prolyl cis-trans isomerase activity, alongside FK-506-binding proteins and parvulins.
- Cyclophilins are ubiquitously expressed in prokaryotic and eukaryotic cells.
Purpose of the Study:
- To review recent data on proteins containing cyclophilin domains (CBD).
- To highlight the expanded understanding of cyclophilin functions beyond their isomerase activity.
Main Methods:
- Literature review of recent studies on cyclophilins and cyclophilin domain-containing proteins.
Main Results:
- Cyclophilins are implicated in diverse cellular functions, including acting as molecular chaperones.
- They play roles in cellular signaling pathways.
- Cyclophilins are associated with the pathogenesis of various human diseases.
Conclusions:
- Cyclophilins exhibit a broader range of biological functions than previously recognized.
- Their involvement in cell signaling, chaperoning, and disease pathogenesis warrants further investigation.

Structural Protein Function
29.9K
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

Mechanical Protein Functions

Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Functional Groups
88.5K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Protein-protein Interfaces
14.7K
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...
