Gammatubuliini

Gammatubuliini is a type of protein that plays a role in the cytoskeleton of cells. Tubulins are the building blocks of microtubules, which are essential components of the cellular structure. Specifically, gammatubuliini is known to be involved in the nucleation and organization of microtubules. It is often found at the centrosome, a key organelle in animal cells that serves as the main microtubule-organizing center. Gammatubuliini's presence at the centrosome is crucial for the proper formation of the spindle apparatus during cell division.

The protein forms a ring-like structure that acts as a template for the assembly of new microtubules. This process ensures that microtubules are initiated at specific sites within the cell and grow in an organized manner. Beyond its role in cell division, gammatubuliini is also implicated in the organization of microtubules in interphase cells, influencing cell shape and intracellular transport. Variations in gammatubuliini function or expression have been linked to certain developmental disorders and cellular abnormalities. Research continues to explore its precise mechanisms and broader biological significance.
