  • Description
    Mouse monoclonal [SLP-32] to MAGI3
  • SpecificityMAGI3 (membrane-associated guanylate cyclase of inverted orientation-3) is a member of the family of membrane-associated guanylate kinases (MAGUKs) that comprise peripheral membrane proteins involved in the formation of specialized cell-cell junctions. MAGI3, as well as other proteins in this family are characterized by three types of protein-protein interaction modules: five PDZ domains, an N-terminal guanylate kinase (GK) domain, and a WW domain. The WW domain, named for two conserved tryptophan residues and first identified as two repeats in mouse YAP65, mediates protein-protein interactions through binding to short proline-rich sequences). MAGI3 and PTEN/MMAC together modulate the kinase activity of AKT/protein kinase B (PKB). MAGI3 positions PTEN/MMAC phosphatase to specific subcellular locations that are involved in the regulation of cell proliferation and survival.

  • FunctionActs as a scaffolding protein at cell-cell junctions, thereby regulating various cellular and signaling processes. Cooperates with PTEN to modulate the kinase activity of AKT1. Its interaction with PTPRB and tyrosine phosphorylated proteins suggests that it may link receptor tyrosine phosphatase with its substrates at the plasma membrane. In polarized epithelial cells, involved in efficient trafficking of TGFA to the cell surface. Regulates the ability of LPAR2 to activate ERK and RhoA pathways. Regulates the JNK signaling cascade via its interaction with FZD4 and VANGL2.
  • Tissue specificityWidely expressed.
  • Sequence similaritiesBelongs to the MAGUK family.
    Contains 1 guanylate kinase-like domain.
    Contains 6 PDZ (DHR) domains.
    Contains 2 WW domains.
  • Post-translational
    Ubiquitinated following interaction with HPV E6 protein, leading to its degradation by the proteasome. Degradation is independent of E6AP ubiquitin ligase complex.
  • Cellular localizationCell membrane. Cell junction > tight junction. Nucleus. Concentrates in specific sites at the plasma membrane and in the nucleus. In epithelial cells, it localizes at tight junctions.
