GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. The results indicate that FliG has a significant tendency to form multimers independently of other flagellar components. The multimerization of FliG is promoted by FliF and also by FliM.
    Title: Biogenesis of the Flagellar Switch Complex in Escherichia coli: Formation of Sub-Complexes Independently of the Basal-Body MS-Ring.
  2. The results indicate a copy number of ~25 for FliG in the complex that regulates the direction of flagellar rotation.
    Title: Architecture of the Flagellar Switch Complex of Escherichia coli: Conformational Plasticity of FliG and Implications for Adaptive Remodeling.
  3. FliG exists predominantly as a monomer in solution but only as domain-swapped polymers in assembled flagellar motors.
    Title: Domain-swap polymerization drives the self-assembly of the bacterial flagellar motor.
  4. The biophysical characterization of this protein is determined.
    Title: Biophysical characterization of the C-terminal region of FliG, an essential rotor component of the Na+-driven flagellar motor.
  5. FliG molecules with pairs of Cys residues in the middle domain formed disulfide-linked dimers and larger multimers, so the middle domains of adjacent subunits are in fairly close proximity and putting constraints on the relative orientation of the domains
    Title: FliG subunit arrangement in the flagellar rotor probed by targeted cross-linking.
