MAGI3 (Membrane Associated Guanylate Kinase, WW, and PDZ Domain Containing 3): MAGI3 is a scaffolding protein involved in the assembly of multiprotein complexes at cell junctions and in signal transduction pathways. It's implicated in cellular processes like epithelial cell polarity and may play a role in cancer development, particularly in the context of cell-cell adhesion and signaling....
