Summary: Enables GDP binding activity; GTP binding activity; and translation initiation factor activity. Contributes to guanyl-nucleotide exchange factor activity. Involved in several processes, including negative regulation of guanyl-nucleotide exchange factor activity; response to amino acid starvation; and response to glucose. Part of eukaryotic translation initiation factor 2 complex and eukaryotic translation initiation factor 2B complex. Human ortholog(s) of this gene implicated in leukoencephalopathy with vanishing white matter 1. Orthologous to human EIF2B1 (eukaryotic translation initiation factor 2B subunit alpha).

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.
