GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. Despite their similarity, DosT and DosS histidine kinases display ligand-specific different primary dynamics during the initial phases of intraprotein signaling, in which the distal tyrosine, present in both proteins, plays an important role.
    Title: Ultrafast ligand dynamics in the heme-based GAF sensor domains of the histidine kinases DosS and DosT from Mycobacterium tuberculosis.
  2. Studies have revealed that the mutation in dosT alone is not directly responsible for the constitutive DosR regulon phenotype.
    Title: Strains of the East Asian (W/Beijing) lineage of Mycobacterium tuberculosis are DosS/DosT-DosR two-component regulatory system natural mutants.
  3. Both sensors DosS and DosT are necessary for wild-type levels of DosR regulon induction, and concomitantly, full induction of the regulon is required for wild-type anaerobic survival.
    Title: Unique roles of DosT and DosS in DosR regulon induction and Mycobacterium tuberculosis dormancy.
  4. This histidine-protein kinase, called DosT, is switched off by binding of oxygen to a heme. The affinity for O2 is Kd = 3 micro-molar. NO and CO will outcompete O2 for binding and blind DosT to O2 regulation.

  5. Heme-binding DosT kinase (Rv2027c) functions as a hypoxia sensor.
