What's a GeneRIF?

Loss of GCN1 causes severe growth retardation and embryonic lethality. GCN1 regulates the eIF2alpha-mediated stress response, cell cycle and cell proliferation.
Title: Ribosome binding protein GCN1 regulates the cell cycle and cell proliferation and is essential for the embryonic development of mice.
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.

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.
