33. Band 3 protein exists as a 95-kDa multipass membrane protein that functions as the primary anion exchanger in erythrocytes. Within the red blood cell (RBC) membrane, band 3 binds to spectrin dimers and tetramers indirectly through ankyrin. The spectrin tetramers are bound together by actin and band 4.1 protein, which also binds to band 3 and glycophorin. Null mutations in band 3 occur in the human population. Which one of the following is most likely to decrease in the absence of band 3 protein?
