Name the proteins found in the tight junctions. Zonula Adherans . The next junction is a complex of thin filaments that form a mat that connect with the membranes. These filaments then extend in a belt like array of all along the top of the cell. What is the adhesion protein at this junction.
Thick fibers loop into a junctional region and the cytoplasm.
The next junction in the series is the Gap junction. Recall from Cell Biology that the Gap junction allow cells to communicate with one another. Small molecules can pass through pore-like transmembrane proteins called connexons. The following photograph shows this diagrammatically. Note that ions, molecules like fluorescein, and second messengers can pass from cell to cell.
