Which among the following defines GPI anchored proteins?
Correct answer: D. Peripheral proteins of plasma membrane
- A. Integral proteins of the plasma membrane
- B. Proteins that bind to ion-gated channels in the plasma membrane
- C. Proteins which randomly bind to lipids of the plasma membrane
- D. Peripheral proteins of plasma membrane
Explanation
Glycosyl phosphatidylinositol (GPI)-anchored proteins are peripheral membrane proteins tethered to the cell through a lipid anchor. GPI-anchored proteins serve many functions in cellular physiology and cell signaling.
