Microtubule-associated protein 6 (MAP6) or stable tubule-only polypeptide (STOP or STOP protein) is a protein that in humans is encoded by the MAP6gene.[5][6]
MAP6 localization is present throughout neuronal maturation and axonal development.[7] It protects microtubules under drug and cold induced depolymerization by reducing the shrinking rate and promoting rescue events. A deficit in MAP6 protein levels is characterized by behavioral impairments, most notably schizophrenia.
