CC -!- FUNCTION: An anti-sigma factor for extracytoplasmic function (ECF)
CC sigma factor SigK. 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 SigK; this
CC should inhibit the interaction of SigK 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 SigK.
CC {ECO:0000250}.
CC -!- PTM: Probably cleaved within the membrane by Rip1 near the cytoplasmic
CC membrane interface.
