Rvb1/Rvb2 proteins couple transcription and translation during glucose starvation.
Title: Rvb1/Rvb2 proteins couple transcription and translation during glucose starvation.
results demonstrate the chaperone-like potential of Rvb1/Rvb2 and suggest a model where binding of multiple clients such as Ino80 stimulates ATP-driven cycling between hexamers and dodecamers, providing iterative opportunities for correct subunit assembly.
Title: Regulation of Rvb1/Rvb2 by a Domain within the INO80 Chromatin Remodeling Complex Implicates the Yeast Rvbs as Protein Assembly Chaperones.
Data show that the 14 different polypeptide containing chromatin-remodeling complex SWR1 contains a single heterohexameric Rvb1/Rvb2 ring that, together with the catalytic subunit Swr1, brackets two independently assembled multisubunit modules.
Title: Molecular architecture of the ATP-dependent chromatin-remodeling complex SWR1.
Existence of a novel role for Tel2, namely in transcription, possibly in cooperation with Rvb2 and involving the existence of physical interactions with the Med15/Gal11 Mediator subunit.
Title: Genetic and physical interactions between Tel2 and the Med15 Mediator subunit in Saccharomyces cerevisiae.
purified endogenous untagged Rvb1/Rvb2 complexes were found as single hexameric rings, similar to the complexes assembled in vitro from purified untagged components
Title: Alternative oligomeric states of the yeast Rvb1/Rvb2 complex induced by histidine tags.
Rvb2p, cooperatively binds single-stranded DNA as monomers. Binding stimulates a slow ATPase activity and supports a 3'- to 5' DNA unwinding activity that requires a 3'-protruding tail >or= 30 nucleotides.
Title: 3'- to 5' DNA unwinding by TIP49b proteins.
Pontin and reptin could acquire distinct structural states to regulate their broad functions as molecular motors and scaffolds for nucleic acids and proteins.
Title: Architecture of the pontin/reptin complex, essential in the assembly of several macromolecular complexes.
These results clearly establish the yeast Rvb1/2 complex as a heterohexameric ATP-dependent DNA helicase and highlight the possible roles played by the Rvb proteins within multiprotein complexes.
Title: Yeast Rvb1 and Rvb2 are ATP-dependent DNA helicases that form a heterohexameric complex.
Rvb2p preferentially binds artificial DNA Holiday junctions like the bacterial RuvAB complex, whereas Rvb1p binds to duplex or cruciform DNA; both proteins also interact with chromatin and play a role in recombination and repair by chromatin remodelling.
