Function

RCSB_ECOLI Component of the Rcs signaling system, which controls transcription of numerous genes. RcsB is the response regulator that binds to regulatory DNA regions. Can function both in an RcsA-dependent or RcsA-independent manner. The system regulates expression of numerous genes, including genes involved in colanic acid capsule synthesis, biofilm formation, cell division and outer membrane proteins synthesis. Also involved, with GadE, in control of glutamate-dependent acid resistance, and, with BglJ, in derepression of the cryptic bgl operon. The RcsB-BglJ activity is probably independent of RcsB phosphorylation.[HAMAP-Rule:MF_00981]^{[1] [2] [3] [4] [5] [6] [7]}
