Summary
Predicted to enable GTP binding activity; GTPase activity; and nucleic acid binding activity. Predicted to be involved in regulation of translational initiation; ribosome assembly; and translational initiation. Is active in synapse. Orthologous to human EIF5B (eukaryotic translation initiation factor 5B). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
