Ribosome assembly protein 1

Gene

RIA1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

GTPase involved in the biogenesis of the 60S ribosomal subunit and translational activation of ribosomes. Together with SDO1, may trigger the GTP-dependent release of TIF6 from 60S pre-ribosomes in the cytoplasm, thereby activating ribosomes for translation competence by allowing 80S ribosome assembly and facilitating TIF6 recycling to the nucleus, where it is required for 60S rRNA processing and nuclear export. Inhibits GTPase activity of ribosome-bound EF-2.3 Publications

Catalytic activityi

GTP + H2O = GDP + phosphate.

Enzyme regulationi

GTPase activity is stimulated in the presence of 60S subunits.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
