Summary
Predicted to enable translation initiation factor binding activity. Predicted to contribute to guanyl-nucleotide exchange factor activity and translation initiation factor activity. Predicted to be involved in several processes, including T cell receptor signaling pathway; negative regulation of guanyl-nucleotide exchange factor activity; and nervous system development. Predicted to act upstream of or within translation. Predicted to be located in cytoplasm. Predicted to be part of eukaryotic translation initiation factor 2B complex. Is expressed in several structures, including adipose tissue; brain; eye; gut gland; and male reproductive gland or organ. Used to study leukoencephalopathy with vanishing white matter. Human ortholog(s) of this gene implicated in leukoencephalopathy with vanishing white matter. Orthologous to human EIF2B4 (eukaryotic translation initiation factor 2B subunit delta).

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.

    Description
    Transcript Variant: This variant (2) lacks a segment spanning the 5' UTR and 5' coding region, compared to variant 1, resulting in translation initiation from an alternate start codon and a shorter protein (isoform 2) with a distinct N-terminus, compared to isoform 1.
