Prefoldins (PFDs) are members of a recently identified, smallmolecularweight protein family able to assemble into molecular chaperonecomplexes. Here we describe an unusually large member of thisfamily, termed URI, that forms complexes with other smallmolecularweight PFDs and with RPB5, a shared subunit of all three RNApolymerases. Functional analysis of the yeast and human orthologsof URI revealed that both are targets of nutrient signalingand participate in gene expression controlled by the TOR kinase.Thus, URI is a component of a signaling pathway that coordinatesnutrient availability with gene expression.
