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.

Involvement in disease

Hepatocellular carcinoma

HCC

A primary malignant neoplasm of epithelial liver cells. The major risk factors for HCC are chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, prolonged dietary aflatoxin exposure, alcoholic cirrhosis, and cirrhosis due to other causes.

None

The gene represented in this entry may be involved in disease pathogenesis.

Sequence similarities

Belongs to the MTUS1 family.

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.

Cellular localization

  • 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.
