Question

Quizplus · Accepted Answer

Spectrin is the principal protein responsible for the skeleton of microfilaments on the inner surface of the RBC membrane. It forms a flexible network that gives the RBC its unique biconcave shape and helps the RBC to withstand the mechanical stress of circulating through narrow capillaries. Actin, glycophorin and ankyrin are also present in the RBC membrane, but they do not play the principal role in the skeleton of microfilaments.
