CC -!- FUNCTION: Acts as an important adapter that promotes epithelial cell
CC polarity and tight junction formation via its interaction with DLG1.
CC Involved in the assembly of protein complexes at sites of cell-cell
CC contact (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Heterodimer; able to heterodimerize via its C-terminal L27
CC domain with LIN7A, LIN7B and LIN7C. Forms a tripartite complex composed
CC of DLG1, MPP7 and LIN7 (LIN7A or LIN7C). Interacts with DLG1 via its N-
CC terminal L27 domain. Interacts with PALS1 and PATJ (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:Q5T2T1};
CC Peripheral membrane protein {ECO:0000250|UniProtKB:Q5T2T1}. Lateral
CC cell membrane {ECO:0000250|UniProtKB:Q5T2T1}; Peripheral membrane
CC protein {ECO:0000250|UniProtKB:Q5T2T1}. Cell junction, tight junction
CC {ECO:0000250|UniProtKB:Q5T2T1}. Cell junction, adherens junction
CC {ECO:0000250|UniProtKB:Q5T2T1}. Cytoplasm, cell cortex
CC {ECO:0000250|UniProtKB:Q5T2T1}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q5T2T1}. Note=In epidermal cells, detected
CC primarily at the lateral cell membrane. {ECO:0000250|UniProtKB:Q5T2T1}.

CC Name=5;
CC IsoId=Q8BVD5-5; Sequence=VSP_031576, VSP_031577;
CC -!- DOMAIN: The phospho-regulated basic and hydrophobic (PRBH) motif is
CC sufficient and important for interaction with phospholipids permitting
CC cortical localization (By similarity). Phosphorylation of the PRBH
CC motif by aPKC inhibits the association of the protein with the cortical
CC membrane (By similarity). {ECO:0000250|UniProtKB:Q5T2T1}.
CC -!- PTM: Phosphorylated by aPKC which promotes dissociation from the cell
CC cortex. {ECO:0000250|UniProtKB:Q5T2T1}.
CC -!- SIMILARITY: Belongs to the MAGUK family. {ECO:0000305}.
