Subcellular location [CC]Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole {ECO:0000269|PubMed:15242618, ECO:0000269|PubMed:19001868}. Cell projection, dendrite {ECO:0000250}. Note=Localizes to centrosomes during early G1 phase where it only associates to the mother centriole and then distributes equally to both mother and daughter centrioles at the onset of S phase.
