Facts about Microtubule-associated tumor suppressor 1.
Together with PTPN6, induces UBE2V2 expression upon angiotensin-II stimulation. Isoform 1 inhibits breast cancer cell regeneration, delays the progression of mitosis by prolonging metaphase and reduces tumor growth.

Ubiquitously expressed (at protein level). Highly expressed in brain. Down-regulated in ovarian carcinoma, pancreas carcinoma, colon carcinoma and head and neck squamous cell carcinoma (HNSCC). Isoform 1 is the major isoform in most peripheral tissues. Isoform 2 is abundant in most peripheral tissues. Isoform 3 is the major isoform in brain, female reproductive tissues, thyroid and heart. Within brain it is highly expressed in corpus callosum and pons. Isoform 6 is brain- specific, it is the major isoform in cerebellum and fetal brain.
Mitochondrion. Golgi apparatus. Cell membrane. Nucleus. In neurons, translocates into the nucleus after treatment with angiotensin-II.; [Isoform 1]: Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytoskeleton, spindle. Localizes with the mitotic spindle during mitosis and with the intercellular bridge during cytokinesis.
