During interphase, forms fibers at the proximal ends of centrioles to maintain centrosome cohesion . During mitosis, dissociates from the centrosome following phosphorylation to allow centrosome separation . Contributes to CROCC/rootletin filament formation .
Subcellular locations: Cytoplasm, Cytoskeleton, Microtubule organizing center, Centrosome, Centriole
Concentrated at the proximal ends of centrioles where it forms fibers . Centrosomal localization becomes weak when cells enter prophase and is significantly decreased in metaphase .
