The following text describes a protein:
Function:
Required for the maturation but not the establishment of septate junctions in developing epithelial cells and is involved in epithelial cell adhesion during septate junction maturation. Plays a role in the proper localization of the septate junction core components pck/mega, kune, Nrx-IV and Nrg during late embryogenesis. Involved in the formation of tricellular junctions which mediate cell contact where three epithelial cells meet but not of bicellular junctions. Required for the accumulation of Gli at tricellular junctions.
Miscellaneous:
MISCELLANEOUS: The name 'bark beetle' derives from the convoluted tracheal branches seen in mutant embryos which resemble the tracks of bark beetle larvae. The name 'anakonda' is also based on the convoluted tracheal tube phenotype of mutant embryos.
Subcellular Localization:
Cell membrane; Single-pass type I membrane protein. Cell junction, septate junction. Cell junction, adherens junction. Note=Found at specialized septate junction structures, known as tricellular junctions (TCJs), that mediate cell contacts at three-cell vertices.
