RIA1/YNL163C Summary Help

Standard Name RIA1 1
Systematic Name YNL163C
Alias EFL1
Feature Type ORF, Verified
Description Cytoplasmic GTPase/eEF2-like factor involved in ribosomal biogenesis; with Sdo1p, a guanine nucleotide exchange factor (GEF), promotes release of Tif6p from 60S ribosomal subunits in the cytoplasm so that they can assemble with 40S subunits to generate mature ribosomes; required for quality control check of newly made large ribosomal subunits before they are released into the pool of translating ribosomes (1, 2, 3, 4, 5, 6, 7)
Name Description RIbosome Assembly 1
