MAGUK p55 subfamily member 5
Membrane protein palmitoylated 5
Protein associated with Lin-7
FunctionMay play a role in tight junctions biogenesis and in the establishment of cell polarity in epithelial cells. May modulate SC6A1/GAT1-mediated GABA uptake by stabilizing the transporter. Required for localization of EZR to the apical membrane of parietal cells and may play a role in the dynamic remodeling of the apical cytoskeleton.
Tissue specificityExpressed in the retina (at protein level).
Sequence similaritiesBelongs to the MAGUK family. Contains 1 guanylate kinase-like domain. Contains 2 L27 domains. Contains 1 PDZ (DHR) domain. Contains 1 SH3 domain.
DomainThe L27 domain 1 functions in targeting to the tight junctions by binding to INADL. The PDZ domain binds to the C-terminus of SC6A1.
Cellular localizationCell membrane. Endomembrane system. Cell junction > tight junction. Localized to the tight junctions of epithelial cells and a subset of intracellular vesicles. In the retina, detected at the outer limiting membrane (OLM), apical to the adherens junction (AJ), where it colocalizes with CRB1. Colocalizes with MPP1 in the retina at the outer limiting membrane (OLM). Localized to the Purkinje cell body and axon.
