Genes affected

RRP8 (HGNC:29030): (ribosomal RNA processing 8) Enables methylated histone binding activity. Involved in several processes, including cellular response to glucose starvation; intrinsic apoptotic signaling pathway by p53 class mediator; and regulation of gene expression. Located in several cellular components, including cytosol; nuclear lumen; and rDNA heterochromatin. Part of chromatin silencing complex. [provided by Alliance of Genome Resources, Apr 2022]
