Summary
Predicted to enable ATP hydrolysis activity and translation initiation factor activity. Acts upstream of or within cellular response to leukemia inhibitory factor. Predicted to be located in perinuclear region of cytoplasm. Is expressed in brain; early conceptus; oocyte; and telencephalon. Orthologous to human EIF4A2 (eukaryotic translation initiation factor 4A2). [provided by Alliance of Genome Resources, Apr 2022]

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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (4) includes an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
