Cell junction facilitating cell to cell communication is?
A. Tight junctions are multi-protein complexes that hold cells of the same tissue together and prevent movement of water and water-soluble molecules between cells.
B. Adherents junctions are large multiprotein complexes that join the actin cytoskeleton to the plasma membrane to form adhesive contacts between cells, or between cells and extracellular matrix.
C. Gap junctions are the main site of cell-cell signalling or communication that allows small molecules to diffuse between adjacent cells.
D. Desmosomes also provide strength and durability to cells and tissues and are located just below adherent’s junctions
E. Brush border is a strip of microvilli on the plasma membrane of an epithelial cell (as in a kidney tubule) that is specialized for absorption.
Thus, the correct answer is Gap function, so option C is correct.
