Anti-PATJ

This gene encodes a protein with multiple PDZ domains. PDZ domains mediate protein-protein interactions, and proteins with multiple PDZ domains often organize multimeric complexes at the plasma membrane. This protein localizes to tight junctions and to the apical membrane of epithelial cells. A similar protein in Drosophila is a scaffolding protein which tethers several members of a multimeric signaling complex in photoreceptors. Protein function: Scaffolding protein that may bring different proteins into adjacent positions at the cell membrane (Probable). May regulate protein targeting, cell polarity and integrity of tight junctions (PubMed:11927608, PubMed:16678097). May regulate the surface expression and/or function of ASIC3 in sensory neurons. May recruit ARHGEF18 to apical cell-cell boundaries (PubMed:22006950). [The UniProt Consortium]
