these results suggest that regulation of the protein kinase phosphorylating the alpha subunit of eif-2 is not the only point at which hemin modulates protein synthesis in reticulocytes and reticulocyte lysates , since a correlation between inhibition of protein synthesis , inhibition of protein kinase activity , and phosphorylation of eif-2 is not observed with all porphyrins .
