This gene encodes member of the prefoldin family of molecular chaperones. The encoded protein functions as a scaffolding protein and plays roles in ubiquitination and transcription, in part though interactions with the RNA polymerase II subunit RPB5. This gene may play a role in multiple malignancies including ovarian cancer and hepatocellular carcinoma. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 22. [provided by RefSeq, Nov 2011],function:Seems to be a scaffolding protein able to assemble a prefoldin-like complex that contains PFDs and proteins with roles in transcription and ubiquitination.,similarity:Belongs to the RNA polymerase II subunit 5-mediating protein family.,subunit:Component of the URI complex that contains PFD2, POLR2E/RPB5, TIP48, TIP49 and URI. Interacts with POLR2E/RPB5 and LRPPRC.,tissue specificity:Ubiquitous.,
