Functional information

Function Uniprot Antitoxin component of a type II toxin-antitoxin (TA) module. A labile antitoxin that counteracts the effect of cognate toxin YafQ. YafQ and DinJ together bind their own promoter, and repress its expression. There are 2 operators with imperfect inverted repeats (IR) in the dinJ promoter, YafQ-(DinJ)2-YafQ only binds to the first (most upstream) of them to repress transcription; binding to a single IR is sufficient for activity in vivo and in vitro. DinJ alone is as potent a transcriptional repressor as the heterotetramer and also only needs to bind 1 IR to act.
Role Repressor
Protein family RelB
Structure (PDB ID) 4Q2U
