چکیده
Erythrocyte protein phosphorylation was from immunologically acquired spheroexamined in membrane preparations of cytosis cells or from cells from patients 25 patients with hereditary spherocytosis with hereditary elliptocytosis. Heating (HS). Reduced phosphorylation in submembranes to 45’C caused negligible strafe polypeptides was observed in 22 inhibition of membrane protein phosHS erythrocyte membranes for both splephorylation, while heating to 50’C extennectomized and nonsplenectomized pasively inhibited phosphorylation. Dephostients. A reduction in labeling was also phorylation of membrane protein that ocobserved in a polypeptide which was curred in isolated membranes was not labeled only in the presence of cAMP. dependent upon cAMP. No reduction was observed in membranes

Phosphorylation of rabbit and human erythrocyte membranes by soluble adenosine 3':5'-monophosphate-dependent and -independent protein kinases.
Previous reports from this laboratory and others have established that both the rabbit and human erythrocyte membranes contain multiple protein kinase and phosphate acceptor activities. We now report that these membranes also contain phosphoryl acceptor sites for the soluble cyclic AMP-dependent and -independent protein kinases from rabbit erythrocytes. The rabbit erythrocyte membrane, which do...
متن کاملOn the mechanism of ATP-induced shape changes in the human erythrocyte membranes: the role of ATP
In the preceding paper (Sheetz, M. and S.J. Singer. 1977. J Cell Biol. 73:638-646) it was shown that erythrocyte ghosts undergo pronounced shape changes in the presence of mg-ATP. The biochemical effects of the action of ATP are herein examined. The biochemical effects of the action of ATP are herein examined. Phosphorylation by ATP of spectrin component 2 of the erythrocyte membrane is known t...
متن کاملInhibition of an Erythrocyte Tyrosine Kinase with Imatinib Prevents Plasmodium falciparum Egress and Terminates Parasitemia
With half of the world's population at risk for malaria infection and with drug resistance on the rise, the search for mutation-resistant therapies has intensified. We report here a therapy for Plasmodium falciparum malaria that acts by inhibiting the phosphorylation of erythrocyte membrane band 3 by an erythrocyte tyrosine kinase. Because tyrosine phosphorylation of band 3 causes a destabiliza...
متن کاملIdentification of the major casein kinase I phosphorylation sites on erythrocyte band 3.
Human erythrocyte band 3 is a major substrate of two red blood cell protein kinases, casein kinase I and p72syk protein tyrosine kinase. Although the phosphorylation sites and physiologic consequences of p72syk phosphorylation have been characterized, little is known regarding casein kinase I phosphorylation. In this report, we identify the major phosphorylation site of casein kinase I. Using i...
متن کاملPhosphorylation of ankyrin decreases its affinity for spectrin tetramer.
The effects of phosphorylation on the interaction between spectrin and ankyrin were investigated. Spectrin and ankyrin were phosphorylated using purified human erythrocyte membrane and cytosolic (casein kinase A) kinases. These two kinases have similar properties as well as activities toward spectrin and ankyrin. Both kinases catalyzed the incorporation of about 2 mol of phosphate/mol of spectr...
