Non-histone chromatin proteins during maturation of avian erythroid cells

W Krajewska et al. Acta Biochim Pol. 1976.

Abstract

1. In chicken erythroid cells (erythroblast, reticulocyte and erythrocyte) maturation was accompanied by a decrease in the content of non-histone chromatin proteins. 2. Phenol-soluble non-histone chromatin proteins (phosphoproteins) from the three cell populations studied, showed differences in the behavior on sodium dodecyl sulphate polyacrylamide-gel electrophoresis, and isoelectric focusing. Phosphoprotein of immature cells had a higher content of fractions of about 86 000 and 23 000 daltons than the phosphoproteins of erythrocytes.
