Microtubule-associated protein RP/EB family member 1 is a protein that in humans is encoded by the MAPRE1 gene.[5][6][7][8]


The protein encoded by this gene was first identified by its binding to the APC (Adenomatous polyposis coli) 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. The protein also associates with components of the dynactin complex and the intermediate chain of cytoplasmic dynein. Because of these associations, it is thought that this protein is involved in the regulation of microtubule structures and chromosome stability. This gene is a member of the RP/EB family.[8]


MAPRE1 has been shown to interact with TERF1.[9]
