"Functions in the initiation of ribosome-mediated translation of mRNA into a polypeptide [goid 3743] [pmid 8688466] [evidence NAS]; Functions in the initiation of ribosome-mediated translation of mRNA into a polypeptide [goid 3743] [pmid 16289705] [evidence IDA]; Stimulates the exchange of guanyl nucleotides by a GTPase. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase [goid 5085] [evidence ISS]; Stimulates the exchange of guanyl nucleotides by a GTPase.
