This is the RNA polymerase interacting domain (RID) of transcription-repair-coupling factor (TRCF), CarD and CarD homologue in Myxococcus xanthus, called CdnL. In Myxococcus xanthus, CdnL is a protein required for the activation of light- and starvation-inducible genes [1]. It interacts with the zinc-binding protein CarG to form a complex that regulates multiple processes in Myxococcus xanthus [4]. CarD is widely distributed among bacteria and represents a distinct class of RNAP binding proteins that regulate transcription and essential processes [4-8]. TRCF displaces RNA polymerase stalled at a lesion, binds to the damage recognition protein UvrA, and increases the template strand repair rate during transcription [3].	Domain
A, B	PF21095	CarD, C-terminal domain (CarD_C)	CarD, C-terminal domain	This entry represents the C-terminal helical domain of CarD from Mycobacterium tuberculosis, a RNAP-binding protein that regulates transcription and essential processes [1-3]. This domain binds DNA in a non-specific manner [4].	Domain
