DOI: 10.1093/nar/gkac449
Abstract: Elongation by RNA polymerase is dynamically modulated by accessory factors. The transcription-repair coupling factor (TRCF) recognizes distressed RNAPs and either rescues transcription or initiates transcription termination. Precisely how TRCFs choose to execute either outcome remains… read more here.
