CC   -!- FUNCTION: An anti-sigma factor for extracytoplasmic function (ECF)
CC       sigma factor SigM. ECF sigma factors are held in an inactive form by an
CC       anti-sigma factor until released by regulated intramembrane proteolysis
CC       (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted
CC       proteolytic cascade to transmit information and elicit cellular
CC       responses. The membrane-spanning regulatory substrate protein is first
CC       cut extracytoplasmically (site-1 protease, S1P), then within the
CC       membrane itself (site-2 protease, S2P, Rip1), while cytoplasmic
CC       proteases finish degrading the regulatory protein, liberating the sigma
CC       factor (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with ECF RNA polymerase sigma factor SigM; this
CC       should inhibit the interaction of SigM with the RNA polymerase
CC       catalytic core. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- DOMAIN: The cytosolic domain interacts with sigma factor SigM.
CC       {ECO:0000250}.
CC   -!- PTM: Probably cleaved within the membrane by Rip1 near the cytoplasmic
CC       membrane interface.
