Function
[OMPR_ECOLI] The N-terminus of this protein is required for the transcriptional expression of both major outer membrane protein genes ompF and ompC; its C-terminal moiety mediates the multimerization of the OmpR protein. As a multimer, it turns on the expression of the ompC gene; as a monomer, it turns on the expression of the ompF gene.

Publication Abstract from PubMed
The C-terminal DNA-binding domain of OmpR, a positive regulator involved in osmoregulation expression of the ompF and ompC genes in Escherichia coli, has a helix-turn-helix variant motif. The 'turn' region, consisting of 11 residues, forms an RNA polymerase contact site.
Escherichia coli positive regulator OmpR has a large loop structure at the putative RNA polymerase interaction site.,Kondo H, Nakagawa A, Nishihira J, Nishimura Y, Mizuno T, Tanaka I Nat Struct Biol. 1997 Jan;4(1):28-31. PMID:8989318[1]
