http://pressbooks-dev.oer.hawaii.edu/biology/chapter/connections-between-cells-and-cellular-activities/ WebA tight junction is a watertight seal between two adjacent animal cells ( Figure ). Proteins (predominantly two proteins called claudins and occludins) tightly hold the cells against each other. Tight junctions form watertight connections between adjacent animal cells.
WebMar 17, 2024 · Gap junctions are cylindrical channels between animal cells that allow small molecules and ions to pass from the inside of one cell to the inside of the adjacent cell. When found in plant cells, similar structures are called plasmodesmata. Cell junctions or junctional complexes, are a class of cellular structures consisting of multiprotein complexes that provide contact or adhesion between neighboring cells or between a cell and the extracellular matrix in animals. They also maintain the paracellular barrier of epithelia and control paracellular transport. Cell junctions are especially abundant in epithelial tissues. Combined with cell adhesion molecules and extracellular matrix, cell junctions help hold animal cells together.
WebA gap junction is a protein-lined pore that allows water and small molecules to pass between adjacent animal cells. Gap junctions develop when a set of six proteins (called connexins) in the plasma membrane arrange …
WebAnimal cells may also contain junctions called desmosomes, which act like spot welds between adjacent epithelial cells. A desmosome involves a complex of proteins. Some of these proteins extend across the membrane, while others anchor the junction within the cell. A non-protein component of enzymes is called the cofactor.
