Summary: The protein encoded by this gene is a member of the membrane-associated guanylate kinase homologue (MAGUK) family. MAGUK proteins participate in the assembly of multiprotein complexes on the inner surface of the plasma membrane at regions of cell-cell contact. The product of this gene may play a role as scaffolding protein at cell-cell junctions. Alternatively spliced transcript variants encoding different isoforms have been identified.

Title: MAGI1, a Scaffold Protein with Tumor Suppressive and Vascular Functions.
MAGI1 was markedly decreased in the Renal cell carcinoma (RCC) and indicated poor survival. Furthermore, we found that MAGI1 suppressed the invasion and migration of human RCC cells. Mechanistic investigations revealed that MAGI1 stabilized the PTEN/MAGI1/beta-catenin complex to inhibit beta-catenin signaling pathway. Moreover, MAGI1 was targeted by miR-520h which was transcriptionally activated by c-Myb.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
