End -binding protein 1 (EB1) is a member of the RP/EB family and was first identified by its binding to the APC protein which is often mutated in familial and sporadic forms of colorectal cancer. This protein localizes to microtubules, especially the growing ends, in interphase cells. During mitosis, the protein is associated with the centrosomes and spindle microtubules. EB1 also associates with components of the dynactin complex and the intermediate chain of cytoplasmic dynein. Because of these associations, it is thought that EB1 is involved in the regulation of microtubule structures and chromosome stability. [rom NCBI GeneID:22919]
