FAMILY

Classic translation factor GTPase family

DESCRIPTION

Also known as EFL1_HUMAN, EFL1, EFTUD1, FAM42A. Involved in the biogenesis of the 60S ribosomal subunit and translational activation of ribosomes. Together with SBDS, triggers the GTP-dependent release of EIF6 from 60S pre-ribosomes in the cytoplasm, thereby activating ribosomes for translation competence by allowing 80S ribosome assembly and facilitating EIF6 recycling to the nucleus, where it is required for 60S rRNA processing and nuclear export. Has low intrinsic GTPase activity. GTPase activity is increased by contact with 60S ribosome subunits. Associates with the 60S ribosomal subunit (PubMed:21536732). Found in a complex consisting of the 60S ribosomal subunit, SBDS and EFL1 (PubMed:22814378). Interacts with SBDS and binds to GTP and GDP; the interaction with SBDS decreases EFL1 affinity for GDP and facilitates GDP release (PubMed:25991726).
