Note(s): Based on ChIp-chip analysis, it was shown that H-NS plays a role in pdeL expression 19151137
Transcription directed across H-NS binding regions relieves H-NS-mediated (and H-NS/StpA-mediated) repression of promoters such as proVp3, pdeLp3, and appYp2, and there is a correlation between transcription across the H-NS-bound region and derepression where RNA polymerase is able to remodel the H-NS complex and/or dislodge H-NS from the DNA and thus relieve repression Rangarajan AA,2018
Evidence: [TIM]
