项目摘要
The long-term objectives of this research are the elucidation of the
mechanism controlling the synthesis of hemoglobin, especially the role of
heme and of protein synthesis in regulating the synthesis of globin and
other proteins in normal and abnormal erythroid cells, and the definition
of the role of heme in the differentiation and maturation of erythroid and
other eukaryotic cells. The specific aims include elucidation of the
mechanisms of regulation of initiation of protein synthesis by
phosphorylation and dephosphorylation, with emphasis on the heme-regulated
elf-2 alpha protein kinase; the interaction of eIf-2 and the reversing
factor, RF, and the role of RF in the recycling of eIF-2 the relationship
between the molecular structure of the heme-regulated eIF-2 alpha kinase
and its activation and activity, and the distribution and function of the
same and similar kinases in erythroid and non-arythroid cells. This
research is relevant not only to the regulation of protein synthesis
generally in eukaryotic cells but specifically is significant for
understanding human anemias characterized by heme deficiency, i.e.,
iron-lack anemia, one of the world's most prevalent disorders, lead
poisoning, and the sideroblastic anemias. The methodology involves in situ
and vitro studies of the components involved in initiation of protein
synthesis, and the purification of the heme-regulated eIF-2 alpha kinase
and analysis of its structure.
