1. Membrane receptor proteins transmit messages between the interior and outside of a cell.
2. It assists in the transport of molecules and ions through the membrane.
3. It protects the integrity of the cell and helps in maintaining its shape.
4. It allows cells to recognize and communicate with one another.

Conclusion

Membrane proteins help in communication between cells, allow nutrients to enter and leave the cells, and maintain the structure of the cell.
