Genes affected
ZNF20 (HGNC:12992): (zinc finger protein 20) Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
ZNF625-ZNF20 (HGNC:48368): (ZNF625-ZNF20 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring zinc finger protein 625 (ZNF625) and zinc finger protein 20 (ZNF20) genes on chromosome 19. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]
