additional information | during transcription after repair, UV irradiation induces a specific Ser-2 phosphorylation of the RNA polymerase II and this phosphorylation is Cockayne syndrome group B protein-dependent. The CDK9 subunit of positive transcription elongation factor b is not responsible for this phosphorylation but instead might play a nonenzymatic role in transcription restart after DNA repair | Homo sapiens | ? | - |
