[[http://www.uniprot.org/uniprot/RELB_ECOLI RELB_ECOLI]] Antitoxin component of a toxin-antitoxin (TA) module. Counteracts the effect of RelE via direct protein-protein interaction, enabling the reversion of translation inhibition. Also acts as an autorepressor of relBE transcription. DNA-binding and repression is stronger when complexed with corepressor RelE. Increased transcription rate of relBE and activation of relE is consistent with a lower level of RelB in starved cells due to degradation of RelB by protease Lon.<ref>PMID:9767574</ref> <ref>PMID:11274135</ref> <ref>PMID:11717402</ref> <ref>PMID:12123459</ref> <ref>PMID:19707553</ref>  Seems to be a principal mediator of cell death in liquid media.<ref>PMID:9767574</ref> <ref>PMID:11274135</ref> <ref>PMID:11717402</ref> <ref>PMID:12123459</ref> <ref>PMID:19707553</ref>
