Genes affected

MPHOSPH8 (HGNC:29810): (M-phase phosphoprotein 8) Enables chromatin binding activity and methylated histone binding activity. Involved in negative regulation of single stranded viral RNA replication via double stranded DNA intermediate; regulation of DNA methylation; and regulation of gene expression. Located in several cellular components, including cytosol; heterochromatin; and nuclear lumen. Part of nucleosome. [provided by Alliance of Genome Resources, Apr 2022]
