Pericentrin

Pericentrin is a 220 kD protein with a putative large coiled-coil domain flanked by noncoiled ends. Present in centrosomes and acentriolar microtubule-organizing centers, where the protein is localized to the pericentriolar material. Pericentrin is probably a conserved integral component of the filamentous matrix of the centrosome involved in the initial establishment of organized microtubule arrays.
