A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a ...

WHEN WE HUMANS got a first glimpse of our genome, we had good reason to question our biological complexity. Many scientists predicted we would possess some 100,000-plus genes, but sequencers finally ...

Researchers at the Centre for Genomic Regulation (CRG) in Barcelona have created the first blueprint of the human spliceosome, the most complex and intricate molecular machine inside every cell. The ...

Humans share a comparable number of protein-coding genes with the simple roundworm Caenorhabditis elegans, yet we are arguably more sophisticated organisms. This difference in complexity is thanks to ...

CEO Abizer Gaslightwala highlights promising ASCO data demonstrating synergy of AKTX-101 with adagasrib in KRAS-driven ...

A conserved region of U6 small nuclear RNA has been implicated in binding an essential metal ion. Is this a glimpse of the spliceosome's catalytic core? Identifying divalent metal ion binding sites in ...

The eukaryotic spliceosome is a multi-megadalton ribonucleoprotein (RNP) complex found in eukaryotic nuclei that catalyzes the removal of introns (non-coding regions) from pre-mRNA and splices exons ...

A sophisticated atomic-level computer simulation has allowed researchers of SISSA and the National Research centre (CNR-IOM - Institute for Materials Manufacturing) to shed light, for the first time, ...

After a decade of work, scientists have completed a molecular model of the human spliceosome, an incredibly complex cellular machine. When an active gene is expressed in a cell, it is transcribed into ...

Gene transcription produces pre-messenger RNAs (pre-mRNA) that are composed of exons and introns as the first RNA species. Subsequent splicing consists of the deletion of introns and the specific ...

In multicellular organisms, the earliest products of transcription, called pre-mRNAs, undergo a molecular makeover before shipping out to the cytoplasm, where the modified mRNAs spell out the recipe ...

New work suggests that Prp8, a highly conserved protein in the heart of the spliceosome, both orients the substrate and participates in catalysis. The U5 snRNP functions in spliceosome assembly as a ...
