| - | [[http://www.uniprot.org/uniprot/ | + | [[http://www.uniprot.org/uniprot/SIGL_MYCTO SIGL_MYCTO]] Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis. [[http://www.uniprot.org/uniprot/RSLA_MYCTU RSLA_MYCTU]] An anti-sigma factor for extracytoplasmic function (ECF) sigma factor SigL. ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut extracytoplasmically (site-1 protease, S1P), then within the membrane itself (site-2 protease, S2P, Rip1), while cytoplasmic proteases finish degrading the regulatory protein, liberating the sigma factor.<ref>PMID:16552079</ref> |
