We previously reported that the RNA endonculease HOE-1 (RNaseZ/ELAC2) is necessary and sufficient for activation of the mitochondrial unfolded protein response (UPRmt) in C. elegans (PMID: 35451962). To comprehensively assess the broader cellular consequences of increased nuclear activity of HOE-1, ...

The exonuclease torpedo Xrn2 loads onto nascent RNA 5’-PO4 ends and chases down pol II to promote termination downstream of polyA sites. We report that Xrn2 is recruited to pre-initiation complexes and “travels” to 3’ ends of genes. Mapping of 5’-PO4 ends in nascent RNA identified Xrn2 loading sites...

S-adenosylmethionine (SAM) is the principal methyl group donor of the cell, required to modify various molecules, including DNA, RNA and proteins. Inside mitochondria, SAM is associated with several steps of mitochondrial gene expression. However, the exact role and significance of these modificatio...
