Clockwise or anticlockwise? Turning the centriole triplets in the right direction!
Centrosomes are small cytoplasmic macromolecular assemblies composed from two major components, centrioles and pericentriolar material, each with its own complex architecture. This organelle is of interest because it plays a role in a number of fundamental cellular processes and defects in these processes have recently been correlated with variety of human disease. Increasingly, what is known about the structure of this organelle has been overshadowed by the increasing wealth of information on its biochemistry. In this short review, we highlight some of the common centriole structural errors found in the literature and define a set of rules that define centriole structure.
