Pre-ribosomal WDR74 module coordinates the early and late pre-rRNA processing stages for the NVL2-mediated regulation of 60S ribosome biogenesis.

WD repeat domain 74 (WDR74) is a nucleolar protein involved in the early stages of pre-60S maturation in the ribosome biogenesis pathway. In later stages, WDR74 interacts with MTR4, an RNA helicase that functions with the exosome nuclease complex, and is dissociated upon ATP hydrolysis by the chaperone-like nuclear VCP-like 2 (NVL2) AAA-ATPase. We previously reported that ATP hydrolysis-defective NVL2 causes aberrant accumulation of WDR74 on the MTR4-exosome complex at the nucleolar periphery and in the nucleoplasm and that this nuclear redistribution of WDR74 leads to the unusual cleavage of the early rRNA precursor within the internal transcribed spacer 1 sequence.

Gene trapping reveals a new transcriptionally active genome element: The chromosome-specific clustered trap region.

Nearly half of the human genome consists of repetitive sequences such as long interspersed nuclear elements. The relationship between these repeating sequences and diseases has remained unclear. Gene trapping is a useful technique for disrupting a gene and expressing a reporter gene by using the promoter activity of the gene.
