A working model for PRC2 regulation of Pol III transcription. (A) A model depicting the role of c-Myc regulation of Pol III transcription through recruiting acetyltransferase TRRAP and GCN5, consisting one of the mechanisms accounting for activation of Pol III transcription (17,18). (B) A proposed model based on findings in the present investigation that PRC2 component EZH2 interacts with TFIIIC complex and is recruited to the promoter of target non-translated RNA genes. EZH2 then trimethylates H3K27 and forms a suppressive complex and represses target non-translated RNA transcription.
