Cell Junctions

Cell Junctions

1. Anchoring Junctions

   • Integral Proteins
     • Cadherins
       • Are fibrous Proteins connected to the microfilaments in the Cytoplasm.
     • Integrins
       • Are composed of two subunits that bind to other proteins, which then bind to the Actin microfilament in the cytoplasm. 

2. Tight Junctions

   • Limits movements of Proteins  Limits movements of materials through the intermembrane space. 

3. Gap Junctions

   • Forms channels Function- Allows a passage for ions or small molecules to communicate.
