GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. Altogether, these data suggest that SigX is indirectly involved in carbon catabolite repression regulation, possibly via its effects on membrane integrity and fluidity.
    Title: The absence of SigX results in impaired carbon metabolism and membrane fluidity in Pseudomonas aeruginosa.
  2. The data presented here suggest that SigX is involved in the outer membrane protein composition, and could be linked to a regulatory network involved in OM homeostasis.
    Title: A proteomic approach of SigX function in Pseudomonas aeruginosa outer membrane composition.
  3. oprF transcription was increased in response to low NaCl or high sucrose concentrations, and this induced transcription was strongly impaired in the absence of SigX.
    Title: Transcription of the oprF gene of Pseudomonas aeruginosa is dependent mainly on the SigX sigma factor and is sucrose induced.
