RNA

ompF mRNA

micF RNA is responsible for osmoregulation of OmpF in low and medium-osmolarity medium; micF RNA also negatively effects OmpF levels in the presence of procaine

PMID:7519595[5]

PMID:11601842[6]

PMID:2478539[7]

when OmpF is made in micF deletion strain, the levels of procaine had little or no effect on amount of OmpF, suggesting micF RNA is needed for OmpF reduction in presence of procaine

Protein

Lrp

Lrp negatively regulates micF transcription

PMID:11601842[6]
