Structural analysis of the messenger RNA cap-binding protein. Presence of phosphate, sulfhydryl, and disulfide groups.


The messenger RNA cap-binding protein (CBP) was isolated from human erythrocyte, rabbit erythrocyte, and rabbit reticulocyte lysate by affinity chromatography on 7-methylguanosine 5'-triphosphate-Sepharose. The specific activity of binding to capped oligonucleotides was similar for the human erythrocyte and rabbit reticulocyte CBPs. Isoelectric focusing of… (More)
