3. Globular regions with specific binding site for the RGD sequences on fibronectin or specific binding sites for specific amino acids on laminin
4. Alpha and beta subunit link to alpha helix and the two cytoplasmic domains interact with actin binding proteins that help integrins assemble actin filaments
46. In order for cells to be mobile, FA must first form but then be broken down. b/c if maintainted, the cell can’t move and stuck at that spot. Say break one at back and make one at front for movement
64. This association organizes intermediate filaments in epithelial cells to help with tensile functions/mechanical stress functions of intermediate filaments
65. Link to plectin proteins that associate with integrins, allowing them to link with intermediate filaments
