Genes affected

CCAR2 (HGNC:23360): (cell cycle and apoptosis regulator 2) Enables RNA polymerase II complex binding activity and enzyme inhibitor activity. Involved in several processes, including regulation of cellular protein metabolic process; regulation of signal transduction; and regulation of transcription, DNA-templated. Located in several cellular components, including mitochondrial matrix; nucleoplasm; and spindle. Part of DBIRD complex. [provided by Alliance of Genome Resources, Apr 2022]
