CC -!- FUNCTION: Plays a role in tight junction biogenesis and in the
CC establishment of cell polarity in epithelial cells (PubMed:16678097,
CC PubMed:25385611). Also involved in adherens junction biogenesis by
CC ensuring correct localization of the exocyst complex protein EXOC4/SEC8
CC which allows trafficking of adherens junction structural component CDH1
CC to the cell surface (By similarity). Plays a role through its
CC interaction with CDH5 in vascular lumen formation and endothelial
CC membrane polarity (PubMed:27466317). Required during embryonic and
CC postnatal retinal development (By similarity). Required for the
CC maintenance of cerebellar progenitor cells in an undifferentiated
CC proliferative state, preventing premature differentiation, and is
CC required for cerebellar histogenesis, fissure formation and cerebellar
CC layer organization (By similarity). Plays a role in the radial and
CC longitudinal extension of the myelin sheath in Schwann cells (By
CC similarity). May modulate SC6A1/GAT1-mediated GABA uptake by
CC stabilizing the transporter (By similarity). Plays a role in the T-cell
CC receptor-mediated activation of NF-kappa-B (PubMed:21479189). Required
CC for localization of EZR to the apical membrane of parietal cells and
CC may play a role in the dynamic remodeling of the apical cytoskeleton
CC (By similarity). Required for the normal polarized localization of the
CC vesicular marker STX4 (By similarity). Required for the correct
CC trafficking of the myelin proteins PMP22 and MAG (By similarity).
CC Involved in promoting phosphorylation and cytoplasmic retention of
CC transcriptional coactivators YAP1 and WWTR1/TAZ which leads to
CC suppression of TGFB1-dependent transcription of target genes such as
CC CCN2/CTGF, SERPINE1/PAI1, SNAI1/SNAIL1 and SMAD7 (By similarity).

CC ECO:0000269|PubMed:25385611, ECO:0000269|PubMed:27466317}.
CC -!- FUNCTION: (Microbial infection) Acts as an interaction partner for
CC SARS-CoV envelope protein E which results in delayed formation of tight
CC junctions and disregulation of cell polarity.
CC {ECO:0000269|PubMed:20861307}.
CC -!- SUBUNIT: Heterodimer with MPP1 (PubMed:17584769). Forms a
CC heterotrimeric complex composed of MMP5, LIN7B and PATJ; the N-terminal
CC L27 domain of MPP5 interacts with the L27 domain of PATJ and the C-
CC terminal L27 domain of MPP5 interacts with the L27 domain of LIN7B
CC (PubMed:22337881). Component of a complex composed of MPP5, CRB1 and
CC MPP4 (PubMed:15914641). Component of a complex whose core is composed
CC of ARHGAP17, AMOT, MPP5/PALS1, PATJ and PARD3/PAR3 (PubMed:16678097).
CC Component of a complex composed of MPP5, CRB1 and EPB41L5
CC (PubMed:17920587). Within the complex, interacts (via HOOK domain) with
CC EPB41L5 (via FERM domain), and interacts with CRB1 (via intracellular
CC domain) (PubMed:17920587). Component of a complex composed of MPP5,
CC MPP3 and CRB1; MPP5 acts as a bridging protein between MPP3 (via
CC guanylate kinase-like domain) and CRB1 (PubMed:16519681). Component of
CC a complex composed of CRB3, MPP5/PALS1 and PATJ (By similarity).
CC Interacts (via PDZ domain) with PATJ (via N-terminus)
CC (PubMed:12527193). Interacts with EZR (By similarity). Interacts (via
CC PDZ domain) with CRB1 (via C-terminal ERLI motif) (PubMed:25385611,
CC PubMed:25760605). While the PDZ domain is sufficient for interaction
CC with CRB1, the adjacent SH3 and guanylate kinase-like domains are
CC likely to contribute to a high affinity interaction (PubMed:25385611).
CC Interacts with WWTR1/TAZ (via WW domain) (PubMed:21145499). Interacts
CC with MPP7 (PubMed:16678097, PubMed:17332497). Interacts (via PDZ
CC domain) with CRB3 (via C-terminus) (By similarity). Interacts with
CC LIN7C (By similarity). Interacts with MPDZ (By similarity). Interacts
CC with PARD6B (By similarity). Interacts with SC6A1 (By similarity).
CC Interacts with CDH5; the interaction promotes MPP5 localization to cell
CC junctions and is required for CDH5-mediated vascular lumen formation
CC and endothelial cell (PubMed:27466317). Interacts with NPHP1 (via
CC coiled coil and SH3 domains) (PubMed:19755384). Interacts with NPHP4
CC (PubMed:19755384). {ECO:0000250|UniProtKB:E2QY99,
