POLR2H, Official Symbol POLR2Hprovided by HGNC Official Full Name RNA polymerase II, I and III subunit Hprovided by HGNC Primary source HGNC:HGNC:9195 See related Ensembl:ENSG00000163882 MIM:606023; AllianceGenome:HGNC:9195 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as RPB8; RPB17; RPABC3 Summary The three eukaryotic RNA polymerases are complex multisubunit enzymes that play a central role in the transcription of nuclear genes. This gene encodes an essential and highly conserved subunit of RNA polymerase II that is shared by the other two eukaryotic DNA-directed RNA polymerases, I and III. Alternative splicing results in multiple transcript variants of this gene.
