Additionally, mRNAs containing internal ribosome entry sites (IRESs), such as the transcripts of the BCL2-associated Athano-Gene 1 (BAG1) and Cold Shock Domain-Containing E1 (CSDE1), show selective reduced translation when RPL11 (uL5) or RPS19 (eS19) levels are reduced in DBA models (58). This evidence concerns the gene CSDE1 and Diamond-Blackfan anemia.
