Protein Information (annotations from UniProt)

Database IDHIV0002250
UniProt IDO15160
Primary gene name(s)POLR1C
Synonym gene name(s)POLR1E
Protein nameDNA-directed RNA polymerases I and III subunit RPAC1
Protein functionDNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Common component of RNA polymerases I and III which synthesize ribosomal RNA precursors and small RNAs, such as 5S rRNA and tRNAs, respectively. RPAC1 is part of the Pol core element with the central large cleft and probably a clamp element that moves to open and close the cleft, By similarity. {ECO:0000250|UniProtKB:P07703, ECO:0000305|PubMed:26151409}.
Subcellular locationNucleus {ECO:0000269|PubMed:26151409}.
