Genes affected

NACC2 (HGNC:23846): (NACC family member 2) Enables several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; histone deacetylase binding activity; and protein homodimerization activity. Involved in several processes, including negative regulation of G1/S transition of mitotic cell cycle by negative regulation of transcription from RNA polymerase II promoter; positive regulation of intrinsic apoptotic signaling pathway in response to DNA damage; and protein homooligomerization. Located in chromatin; mitochondrion; and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]
