May be involved in microtubule organization and stabilization.
Subcellular locations: Cytoplasm, Cytoskeleton, Microtubule organizing center, Centrosome, Nucleus, Cytoplasm, Cleavage furrow
Cell-cycle-dependent association with the centrosome. Colocalizes with a subpopulation of microtubules. Does not associate with microtubules during mitosis but reassociates with microtubules during cytokinesis. Localizes to the central portions of a small subset of microtubules in interphase cells and a subpopulation of microtubules in the cleavage furrow, not present in the mitotic spindle (By similarity).
