Genes affected
RRP1B (HGNC:23818): (ribosomal RNA processing 1B) Enables transcription coactivator activity. Involved in several processes, including cellular response to virus; positive regulation by host of viral transcription; and positive regulation of transcription by RNA polymerase II. Located in chromosome; granular component; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
