Summary
Centrins, also known as caltractins, are versatile calcium-binding proteins found in eukaryotes. This review focuses on the structures and functions of centrins in unicellular organisms.
Area of Science:
- Biochemistry
- Molecular Biology
- Structural Biology
Background:
- Centrins (caltractins) are ubiquitous eukaryotic proteins containing EF hands.
- They possess a dumbbell-shaped structure with two similar domains linked by an alpha-helix.
- Their small size and functional diversity make them excellent models for structure-function studies.
Purpose of the Study:
- To review the structural and functional characteristics of centrins.
- To focus on centrins within unicellular organisms.
Main Methods:
- Literature review of existing research on centrins.
- Analysis of structural and functional data from unicellular eukaryotes.
Main Results:
- Centrins exhibit conserved structural features, including EF hands for calcium binding.
- Functional roles vary across unicellular organisms, highlighting specialization.
- Structural insights reveal how domain organization relates to function.
Conclusions:
- Centrins are crucial calcium-binding proteins with diverse roles in unicellular eukaryotes.
- Understanding centrin structure provides insights into protein-protein interactions and cellular processes.
- Further research on centrins can illuminate fundamental biological mechanisms.

01:13Centrioles and Centrosomes
Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.

01:13Cell Diversity
The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

02:25Centrosome Duplication
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:57Protein Complexes with Interchangeable Parts
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
