Facts about Calmodulin-regulated spectrin-associated protein 1.
Acts on free microtubule minus-ends which are not restricted by microtubule- nucleating proteins or other factors and shields microtubule minus-ends from depolymerization (PubMed:24486153, PubMed:24706919). Compared to CAMSAP2 and CAMSAP3, monitors along the growing tips of minus-end microtubules without significantly affecting the polymerization rate: orbits in the very tip of the microtubules minus-end and acts as a minus-end tracking protein (- TIP) which dissociates from microtubules after enabling tubulin incorporation (PubMed:24486153, PubMed:24706919).

Cytoplasm, cytoskeleton. Associates with the minus-end of microtubules (PubMed:24486153, PubMed:24706919). In contrast to CAMSAP2 and CAMSAP3, does not form stretches of decorated microtubule minus-ends (PubMed:24486153, PubMed:24706919).
