Regulates microtubule organization and stabilization. Promotes microtubule growth and bundling formation and stabilizes microtubules by increasing intense acetylation of microtubules (, ). Both tubulin-binding and homodimer formation are required for NCKAP5L-mediated microtubule bundle formation .
Subcellular locations: Cytoplasm, Cytoskeleton, Microtubule organizing center, Centrosome
Localizes to microtubule plus ends (, ). Associates with centrosomes during interphase, but dissociates from these structures from the onset of mitosis .
