Influence of glucagon and cyclic adenosine 3':5'-monophosphate on the phosphorylation of rat liver ribosomal protein S6
A. M. Gressner and I. G. Wool
The administration of glucagon, adenosine 3':5'-monophosphate, or
N6,O2'-dibutyryl adenosine 3':5'-monophosphate caused an increase in the
phosphorylation of rat liver ribosomes. The increase (approximately 3-fold)
was in the protein of the small ribosomal subunit. The proteins were
separated by two-dimensional polyacrylamide gel electrophoresis and
radioautographs were made of the gels. The effect of the hormone and of the
nucleotides was entirely due to an increase in the phosphorylation of the
40 S ribosomal subunit protein S6.
