"Protein/gene_name: theta 1-globin. Comments: Higher levels of theta 1 mRNA were found in fetal liver cells compared with trace amounts in reticulocytes and normal adult bone marrow cells. These data clearly show that in contrast to the embryonic and adult patterns of expression of zeta and alpha-globin genes, respectively, theta 1-globin gene displays a different profile, being active predominantly during the early stages of ontogeny, switching to lower levels of expression in adulthood."xsd:string
