Summary: Predicted to enable mRNA binding activity; translation initiation factor activity; and translation initiation factor binding activity. Acts upstream of or within in utero embryonic development; male germ cell proliferation; and male gonad development. Is active in synapse. Is expressed in several structures, including blastocyst; colon; early embryo; gonad; and liver. Orthologous to human EIF2S2 (eukaryotic translation initiation factor 2 subunit beta).

What's a GeneRIF?

This study provides evidence that even a mild mutation in eIF2B, leading merely to a ~ 20% decrease in its enzymatic activity, is associated with mitochondrial malfunction caused by defective oxphos and with increased mitochondrial biogenesis compensating for energetic needs.
Title: Mutant eIF2B leads to impaired mitochondrial oxidative phosphorylation in vanishing white matter disease.
GCN2 activation increased phosphorylation of its substrate eIF2alpha and the induction of the integrated stress response master regulator, ATF4.
Title: Perturbations in actin dynamics reconfigure protein complexes that modulate GCN2 activity and promote an eIF2 response.
BMP-2 stimulates differentiation of myoblasts into osteoblasts via the PERK-eIF2alpha-ATF4 pathway but in addition stimulates Tmem119, which itself increases ATF4
Title: Involvement of the osteoinductive factors, Tmem119 and BMP-2, and the ER stress response PERK-eIF2α-ATF4 pathway in the commitment of myoblastic into osteoblastic cells.
This study extends our understanding of the roles played by GCN1 in GCN2 activation induced by a variety of stress arrangements and suggests that IMPACT and YIH1 use similar mechanisms for regulating this eIF2alpha kinase.
Title: Evolutionarily conserved IMPACT impairs various stress responses that require GCN1 for activating the eIF2 kinase GCN2.
Study found that the incidence of testicular germ cell tumor in affected males was reduced 2-fold in mice that were partially deficient for Eif2s2 and embryonic lethality occurred near the time of implantation in mice that were fully deficient for Eif2s2.
Title: Deletion of eIF2beta suppresses testicular cancer incidence and causes recessive lethality in agouti-yellow mice.

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.
