the existence of both protein kinase ( s ) and alkaline phosphatase activities in placental free cytoplasmic mrnps might suggest that a balance between phosphorylation , specifically on tyrosine residues , and dephosphorylation states of some of the mrnp-proteins is relevant for their physiological functions , and may therefore play a role in the regulation of mrnps ' metabolism and , consequently , in mrna translation .
