Breakdown of band 3, observed during normal erythrocyte aging in situ and in some diseases involving erythrocytes, is associated with an increase in K<jats:sub>m<\/jats:sub> and a decrease in V<jats:sub>max<\/jats:sub> of sulfate self-exchange, and with an increase in K<jats:sub>m<\/jats:sub> and V<jats:sub>max<\/jats:sub> of glucose efflux. Erythrocytes containing a high molecular weight form of band 3 exhibit an increase in V<jats:sub>max<\/jats:sub> of sulfate exchange and a decrease in V<jats:sub>max<\/jats:sub> of glucose efflux. Identical transport characteristics are observed in abnormal band-3-containing erythrocytes from individuals with familial amyotrophic chorea with acanthocytosis. A third band 3 alteration, fast-aging band 3, exhibits decreased V<jats:sub>max<\/jats:sub> of sulfate exchange and an increase in K<jats:sub>m<\/jats:sub> and decrease in V<jats:sub>max<\/jats:sub> of glucose efflux. Changes in band 3 structure that are the result of unstable hemoglobin or a deficiency in glucose-6-phosphate dehydrogenase and that do not affect anion transport have no effect on glucose transport characteristics. These data indicate the existence of a functional relationship between the membrane-spanning, anion-transport domain of band 3 and glucose transport in human erythrocytes. Antibodies to synthetic peptides reveal structural changes in membranes from the three inborn band 3 alterations and in band 3 itself in membranes from fast-aging band 3. Thus, immunological data suggests a structural relationship between anion and glucose transporters.Key words: red cell, anion transport, membrane proteins, aging, choreoacanthocytosis, anemia. <\/jats:p>","DOI":"10.1139\/o90-205","type":"journal-article","created":{"date-parts":[[2009,12,23]],"date-time":"2009-12-23T19:38:58Z","timestamp":1261597138000},"page":"1419-1427","source":"Crossref","is-referenced-by-count":19,"title":["Alterations of band 3 transport protein by cellular aging and disease: erythrocyte band 3 and glucose transporter share a functional relationship"],"prefix":"10.1139","volume":"68","author":[{"given":"Gieljan J.
