Regulation of ribosome biogenesis: where is TOR?

Cell Metab. 2006 Oct;4(4):259-60. doi: 10.1016/j.cmet.2006.09.002.

Abstract

Li et al., (2006) have shown that TOR complex 1 in yeast binds directly to the rDNA promoter and thereby activates Pol I-dependent synthesis of 35S RNA. This is an important advance in the understanding of how ribosome biogenesis is regulated in response to environmental conditions.
