- Background
- Mitochondrial tumor suppressor 1 (MTSG1) or Microtubule-Associated Scaffold Protein 1 (MTUS1) is a candidate tumor suppressor protein encoded by the MTUS1 gene in humans. It is mapped to 8p22. This gene encodes a protein which contains a C-terminal domain able to interact with the angiotension II (AT2) receptor and a large coiled-coil region allowing dimerization. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. One of the transcript variants has been shown to encode a mitochondrial protein that acts as a tumor suppressor and partcipates in AT2 signaling pathways. Other variants may encode nuclear or transmembrane proteins but it has not been determined whether they also participate in AT2 signaling pathways.

- Immunogen
- E.coli-derived human MTUS1 recombinant protein (Position: D1038-N1236).
- Clonality
- Polyclonal
- Tissue Specificity
- 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.
- Applications
- ELISA,IF,ICC,WB
- Purification
- Immunogen affinity purified.
- Concentration
- Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.
- Form
- Lyophilized
- Reconstitution
- Add 0.2ml of distilled water will yield a concentration of 500ug/ml.
- Function
- Cooperates with AGTR2 to inhibit ERK2 activation and cell proliferation. May be required for AGTR2 cell surface expression. Together with PTPN6, induces UBE2V2 expression upon angiotensin-II stimulation. Isoform 1 inhibits breast cancer cell proliferation, delays the progression of mitosis by prolonging metaphase and reduces tumor growth.
- Components
- Each vial contains 4mg Trehalose, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg NaN3.
