The molecular mechanisms by which S10 can act as a translation or a transcription factor are not understood. We used complementation assays and recombineering to delineate regions of S10 dispensable for antitermination, and determined the crystal structure of a transcriptionally active NusB-S10 complex. In this complex, S10 adopts the same fold as in the 30S subunit and is blocked from simultaneous association with the ribosome. Mass spectrometric mapping of UV-induced crosslinks revealed that the NusB-S10 complex presents an intermolecular, composite, and contiguous binding surface for RNAs containing BoxA antitermination signals. Furthermore, S10 overproduction complemented a nusB null phenotype. These data demonstrate that S10 and NusB together form a BoxA-binding module, that NusB facilitates entry of S10 into the transcription machinery, and that S10 represents a central hub in processive antitermination."],["dc.identifier.doi","10.1016/j.molcel.2008.10.028"],["dc.identifier.isi","000262184200009"],["dc.identifier.pmid","19111659"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/52668"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Cell Press"],["dc.relation.issn","1097-2765"],["dc.title","Structural and Functional Analysis of the E. coli NusB-S10 Transcription Antitermination Complex"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The CASK CaM-kinase domain is presumed to be a catalytically inactive pseudokinase because it lacks the canonical DFG motif required for Mg2+ binding that is thought to be indispensable for kinase activity. Here we show, however, that CASK functions as an active protein kinase even without Mg2+ binding. High-resolution crystal structures reveal that the CASK CaM-kinase domain adopts a constitutively active conformation that binds ATP and catalyzes phosphotransfer without Mg2+. The CASK CaM-kinase domain phosphorylates itself and at least one physiological interactor, the synaptic protein neurexin-1, to which CASK is recruited via its PDZ domain. Thus, our data indicate that CASK combines the scaffolding activity of MAGUKs with an unusual kinase activity that phosphorylates substrates recuited by the scaffolding activity. Moreover, our study suggests that other pseudokinases (10% of the kinome) could also be catalytically active."],["dc.description.sponsorship","NIMH NIH HHS [R37 MH052804, R37 MH052804-08, R37 MH52804-08]"],["dc.identifier.doi","10.1016/j.cell.2008.02.036"],["dc.identifier.isi","000255052000021"],["dc.identifier.pmid","18423203"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/54500"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Cell Press"],["dc.relation.issn","0092-8674"],["dc.title","CASK functions as a Mg2+-independent neurexin kinase"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Brr2 exhibits an unusual architecture, including an similar to 500-residue N-terminal region, whose functions and molecular mechanisms are presently unknown, followed by a tandem array of structurally similar helicase units (cassettes), only the first of which is catalytically active. Here, we show by crystal structure analysis of full-length Brr2 in complex with a regulatory Jab1/MPN domain of the Prp8 protein and by cross-linking/mass spectrometry of isolated Brr2 that the Brr2 N-terminal region encompasses two folded domains and adjacent linear elements that clamp and interconnect the helicase cassettes. Stepwise N-terminal truncations led to yeast growth and splicing defects, reduced Brr2 association with U4/U6.U5 tri-snRNPs, and increased ATP-dependent disruption of the tri-snRNP, yielding U4/U6 disnRNP and U5 snRNP. Trends in the RNA-binding, ATPase, and helicase activities of the Brr2 truncation variants are fully rationalized by the crystal structure, demonstrating that the N-terminal region autoinhibits Brr2 via substrate competition and conformational clamping.

Brr2 is regulated in part by the spliceosomal Prp8 protein by an unknown mechanism. We demonstrate that the RNase H (RH) domain of yeast Prp8 binds U4/U6 small nuclear RNA (snRNA) with the single-stranded regions of U4 and U6 preceding U4/U6 stem I, contributing to its binding. Via cross-linking coupled with mass spectrometry, we identify RH domain residues that contact the U4/U6 snRNA. We further demonstrate that the same single-stranded region of U4 preceding U4/U6 stem I is recognized by Brr2, indicating that it translocates along U4 and first unwinds stem I of the U4/U6 duplex. Finally, we show that the RH domain of Prp8 interferes with U4/U6 unwinding by blocking Brr2's interaction with the U4 snRNA. Our data reveal a novel mechanism whereby Prp8 negatively regulates Brr2 and potentially prevents premature U4/U6 unwinding during splicing. They also support the idea that the RH domain acts as a platform for the exchange of U6 snRNA for U1 at the 59 splice site.
