Proteins in the Centrosome
Home page of the Centrosome 3D Consolider collaboration
The Centrosome is a large and complex cellular body that organizes the microtubules and performs vital functions in the regulation of cell cycle, the division and differentiation of animal cells, and is present in simpler form in other eukaryotic cells. In human cells it is composed by hundreds of proteins, which are highly disordered, coiled-coil and phosphorylated and form a large number of protein-protein interactions. These properties probably contribute to its versatility in space (cell type) and time (development). We are interested in the evolution of centrosomal proteins and their properties, mainly structural disorder.
