Unconventional prefoldin RPB5 interactor, also called URI1, is a protein that in humans is encoded by the URI1 gene.{{cite journal | vauthors = Van Leuven F, Torrekens S, Moechars D, Hilliker C, Buellens M, Bollen M, Delabie J | title = Molecular cloning of a gene on chromosome 19q12 coding for a novel intracellular protein: analysis of expression in human and mouse tissues and in human tumor cells, particularly Reed-Sternberg cells in Hodgkin disease | journal = Genomics | volume = 54 | issue = 3 | pages = 511–20 | date = Feb 1999 | pmid = 9878255 | doi = 10.1006/geno.1998.5609 }}{{cite journal | vauthors = Dorjsuren D, Lin Y, Wei W, Yamashita T, Nomura T, Hayashi N, Murakami S | title = RMP, a Novel RNA Polymerase II Subunit 5-Interacting Protein, Counteracts Transactivation by Hepatitis B Virus X Protein | journal = Mol Cell Biol | volume = 18 | issue = 12 | pages = 7546–55 | date = Dec 1998 | pmid = 9819440 | pmc = 109335 | doi = 10.1128/mcb.18.12.7546}}{{cite web | title = Entrez Gene: C19orf2 chromosome 19 open reading frame 2| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=8725}}

Function

The protein encoded by this gene binds to RNA polymerase II subunit 5 (RPB5) and negatively modulates transcription through its binding to RPB5. The encoded protein seems to have inhibitory effects on various types of activated transcription, but it requires the RPB5-binding region. This protein acts as a corepressor. It is suggested that it may require signaling processes for its function or that it negatively modulates genes in the chromatin structure. Two alternatively spliced transcript variants encoding different isoforms have been described for this gene.
