Cytoplasmic 60S subunit biogenesis factor REI1

UniProtKB accession:  P38344

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Pre-60S-associated factor involved in the cytoplasmic maturation of the 60S subunit. Involved in the dissociation and recycling of other late pre-60S factors like ARX1, TIF6 and ALB1 before newly synthesized large ribosomal subunits enter translation. Cooperates with the co-chaperone JJJ1 in the release of the nuclear-export factor ARX1. May act redundantly with REH1 to directly promote a stabilizing structural rearrangement in cytoplasmic 60S subunit maturation independent on ARX1 recycling.
