MSH: A eukaryotic initiation factor that interacts with the 40S initiation complex and promotes the hydrolysis of the bound GTP. The hydrolysis of GTP causes the release of EUKARYOTIC INITIATION FACTOR-2 and EUKARYOTIC INITIATION FACTOR-3 from the 40S subunit and the subsequent joining of the 60S ribosomal subunit to the 40S complex to form the functional 80S initiation complex
