Biological Activity
PCNT (pericentrin) is associated with various centrosomal activities. It forms a functional complex with pericentriolar material 1 (PCM1) in cells, which is responsible for centrosome function. In association with DISC1 (Disrupted-In-Schizophrenia 1), PCNT plays a vital role in the microtubule network assembly. During cytoskeleton assembly, it binds to the microtubule nucleation component, γ-tubulin, and plays a crucial role in the cell-cycle progression by directing a proper spindle organization. It has been observed th at low level of PCNT alters the arrangement of mitotic spindles and leads to missegregation of chromosomes. Mutation in PCNt gene causes two autosomal recessive disorders named Seckel syndrome and Majewski osteodysplastic primordial dwarfism type II (MOPD II).
