What's a GeneRIF?

modulation of eIF2Bepsilon expression may be sufficient to correct deficits in skeletal muscle protein synthesis associated with sepsis and other muscle-wasting conditions
Title: Ectopic expression of eIF2Bepsilon in rat skeletal muscle rescues the sepsis-induced reduction in guanine nucleotide exchange activity and protein synthesis.
oligodendroglial-derived cells expressing a mutated eIF2B5 constantly use their stress response mechanism as an adaptation mean in order to survive
Title: A point mutation in translation initiation factor 2B leads to a continuous hyper stress state in oligodendroglial-derived cells.
Data show that activation of mTORC1 is necessary and sufficient to stimulate eIF2Bepsilon mRNA translation.
Title: Activation of the mammalian target of rapamycin complex 1 is both necessary and sufficient to stimulate eukaryotic initiation factor 2Bvarepsilon mRNA translation and protein synthesis.
mTOR signaling and eIF2Bepsilon mRNA translation are linked and could have roles in the stimulation of protein synthesis following acute resistance exercise
Title: Resistance exercise increases muscle protein synthesis and translation of eukaryotic initiation factor 2Bepsilon mRNA in a mammalian target of rapamycin-dependent manner.

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.
