UniProt ID: Q8JHF4
FUNCTION: May play a role in tight junctions biogenesis and in the establishment of cell polarity in epithelial cells (By similarity). Functions in cellular patterning of the retina. {ECO:0000250, ECO:0000269|PubMed:11992120}.
SUBCELLULAR LOCATION: Apical cell membrane {ECO:0000269|PubMed:11992120}; Peripheral membrane protein {ECO:0000269|PubMed:11992120}. Cell junction, tight junction {ECO:0000269|PubMed:11992120}. Note=Localizes to the apical region of the cell membrane, in the vicinity of junctional complexes in the neuroepithelium and the photoreceptor layer. Enriched in the areas immediately apical to the adherens junctions-associated actin bundles.
TISSUE SPECIFICITY: Expressed in the retina and in the neural tube. {ECO:0000269|PubMed:11992120}.
DEVELOPMENTAL STAGE: Expressed early in development. {ECO:0000269|PubMed:11992120}.
DOMAIN: The PDZ domain is required for apical location. {ECO:0000269|PubMed:11992120}.
SIMILARITY: Belongs to the MAGUK family. {ECO:0000305}.
