Summary
Predicted to enable RNA binding activity; ribosomal small subunit binding activity; and translation initiation factor activity. Predicted to be involved in translational initiation. Predicted to be part of eukaryotic 43S preinitiation complex. Orthologous to human EIF1B (eukaryotic translation initiation factor 1B). [provided by Alliance of Genome Resources, Apr 2025]

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.
