Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000530
UniProt IDO15446
Primary gene name(s)CD3EAP
Synonym gene name(s)ASE1, CAST, PAF49
Protein nameDNA-directed RNA polymerase I subunit RPA34
Protein functionDNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase I which synthesizes ribosomal RNA precursors. Isoform 1 is involved in UBTF-activated transcription, presumably at a step following PIC formation.; FUNCTION: Isoform 2 has been described as a component of preformed T-cell receptor, TCR complex.
Subcellular locationNucleus, nucleolus {ECO:0000269|PubMed:9426281}. Chromosome {ECO:0000269|PubMed:9426281}. Note=Found at the fibrillar centers of the nucleolus in interphase and during cell division it is localized to the nucleolus organizer regions of the chromosomes.
