Which of the following protein molecule is responsible for cell-to-cell adhesion?
High-Yield Explanation
Ans. D. FibronectinCell adhesion molecules are:1. Integrins2. Cadherins3. Selectinsa. Integrins are major class of receptors within ECM (extra cellular matrix), mediates cell ECM interaction with collagen, fibrinogen, fibronectin.b. Fibronectin is involved in cell adhesion, growth, migration and differentiation. it plays crucial role in wound healingc. Enactin is a component of basement membrane it connects the network formed by collagen and laminin.d. Laminin is also a basement membrane protein.
