[Phosphorylation of proteins of mRNP-particles of rabbit reticulocytes and their possible role in translation regulation].
Protein kinase activity was found associated with free mRNP particles of rabbit reticulocytes. This enzyme was able to transfer phosphate group(s) from ATP to at least nine proteins of mRNP. Rabbit reticulocytes postmitochondrial supernatant proves the existence of protein phosphatase activity specifically dephosphorylating some mRNP proteins. The role of mRNP proteins phosphorylation--dephosphorylation in translation process is discussed.
