Cell-to-cell junctions

Michaela Tiffany


Surface markers

Structure: Variable, integral proteins or glycolipids in plasma membrane

Function: Identify the cell

Example: MHC complexes, blood groups, antibodies


Septate junctions/tight junctions

Structure: Tightly bound,


, fibrous claudin protein seal that surrounds the cell

Function: Holds cells together such that materials pass through not between the cells

Example: Junctions between epithelial cells in the gut


Adhesive junction (Desmosome)

Structure: Variant


, desmocollins, blind to intermediate filaments of cytoskeleton

Function: Creates strong flexible connections between cells

Found in vertebrates

Example: Epithelium


Adhesive junction(Adherens junctions)

Structure: Classical


, bind to microfilaments of cytoskeletonFunction: Connects cells together

Oldest form of cell junction

Found in all multicellular organisms

Example: Tissues with high mechanical stress, such as the skin


Adhesive junction (


, focal adhesion)

Structure: Integrin proteins bind cell to extracellular matrix

Function: Provide attachment to a substrate

Example: Involved in cell movement and important during development


Communicating junction (Gap junction)

Structure: Six transmembrane connexons/pannexin proteins creating a pore that connects cells

Function: Allows passage of small molecules from cell to cell in a tissue

Example: Excitable tissue such as heart muscle


Communicating junction (Plasmodesmata)

Structure: Cytoplasmic connections between gaps in adjoining plant cell walls

Function: Communicating junctions between plant cells

Example: Plant tissues
