Answer:
The correct answer is 4. Anchoring cells in position.
Cell adhesion proteins are the class of proteins found on the surface of the cell and are involved in the process of cell adhesion.
Cell adhesion is the process by which cell binds to the other cell or to the extra cellular matrix with the help of cell adhesion molecules (CAMs) or proteins.
CAMs show three major types of interactions to achieve cell adhesion.
- Homophilic in which CAMs bind with the same CAMs.
- Heterophilic in which CAM of one cell binds to that of of other cell.
- In third type of interaction, CAMs of two cells bind to a mutual extracellular ligand.
Cell adhesion proteins are also called as molecular glue as they help in anchoring the cells in the position.
