Polycomb group (PcG) genes were initially described in Drosophila melanogaster as regulators of the homeobox gene. Four mammalian homologues, mel-18, bmi-1, M33 and rae-28, are analyzed in this study. They not only regulate mammalian homeotic genes by analogy with their Drosophila counterparts, but also have some influence on the growth and differentiation of B lymphocytes. Here we report that these four mammalian PcG genes are rapidly induced after antigen-receptor cross-linking in B cells. Thus we would like to propose that mammalian PcG genes can be categorized as a new type of immediate early gene.
多梳蛋白家族(PcG)基因最初在黑腹果蝇中被描述为同源异型盒基因的调节因子。本研究分析了四种哺乳动物同源物,即mel-18、bmi-1、M33和rae-28。它们不仅通过与其果蝇对应物类比来调节哺乳动物的同源异型基因,而且对B淋巴细胞的生长和分化也有一定影响。在此我们报告,这四种哺乳动物PcG基因在B细胞中抗原受体交联后会迅速被诱导。因此我们提议将哺乳动物PcG基因归类为一种新型的立即早期基因。
