Which among the following defines GPI-anchored proteins?
Correct answer: D. Peripheral proteins of membrane
- A. Integral proteins of the plasma membrane
- B. Proteins that bind to ion gated channels in plasma membrane
- C. Proteins which randomly bind to lipids of membrane
- D. Peripheral proteins of membrane
Explanation
GPI-anchored proteins can indeed be considered a specific type of peripheral membrane protein. The term "GPI-anchored" refers to the method by which these proteins are attached to the lipid bilayer. They are linked to the membrane via a glycosylphosphatidylinositol (GPI) anchor, which allows them to be peripherally associated with the membrane surface. On the other hand, the rest of the options are incorrect.
