Structural basis of Nipah virus RNA synthesis

Authors Sala FA, Ditter K, Dybkov O, Urlaub H, Hillen HS Journal Nature Communications Citation Nat Commun. 2025 Mar 6;16(1):2261. Abstract Nipah virus (NiV) is a non-segmented negative-strand RNA virus (nsNSV) with high pandemic potential, as it frequently causes zoonotic outbreaks and can be transmitted from human to human. Its

FASTKD5 processes mitochondrial pre-mRNAs at non-canonical cleavage sites

Authors Antonicka H, Weraarpachai W, Vučković A, Hillen HS, Shoubridge EA Journal BioRxiv Citation bioRxiv 2024.07.18.603998. Abstract The regulation of mammalian mitochondrial gene expression is largely post-transcriptional and the first step in translating the 13 polypeptides encoded in mtDNA is endonucleolytic cleavage of the primary polycistronic transcripts. As the rRNAs

The molecular machinery for maturation of primary mtDNA transcripts

Authors Vučković A, Freyer C, Wredenberg A, Hillen HS Journal Human Molecular Genetics Citation Hum Mol Genet. 2024 May 22;33(R1):R19-R25. Abstract Human mitochondria harbour a circular, polyploid genome (mtDNA) encoding 11 messenger RNAs (mRNAs), two ribosomal RNAs (rRNAs) and 22 transfer RNAs (tRNAs). Mitochondrial transcription produces long, polycistronic transcripts that

Structural and mechanistic basis of RNA processing by protein-only ribonuclease P enzymes

Authors Bhatta A, Hillen HS Journal Trends in Biochemical Sciences Citation Trends Biochem Sci. 2022 Jun 18:S0968-0004(22)00139-6. Abstract Ribonuclease P (RNase P) enzymes are responsible for the 5′ processing of tRNA precursors. In addition to the well-characterised ribozyme-based RNase P enzymes, an evolutionarily distinct group of protein-only RNase Ps exists.
