title: Protein phosphorylation in erythroid cell development.
abstract: Changes in the phosphorylation of proteins during erythroid cell development have been investigated by assaying the activity of three protein kinases in circulating reticulocytes, and dividing and non-dividing erythroblasts obtained from the bone marrow of anaemic rabbits. Kinase activities decreased during erythroid cell development, but protein phosphorylation was generally limited by substrate availability rather than enzyme activity. Using permeabilized cells some changes in the patterns of proteins phosphorylated by [gamma-32P]ATP were observed during erythroid cell development.
