About Eif2ak3

Chromosome 6: 70,821,499-70,882,229 forward strand.GRCm39:CM000999.3

This gene has 5 transcripts (splice variants), 197 orthologues, 8 paralogues and is associated with 41 phenotypes. Ubiquitous expression in placenta adult (RPKM 1.8), colon adult (RPKM 7.9) and 28 other tissues.

Summary

The protein encoded by this gene phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2, leading to its inactivation, and thus to a rapid reduction of translational initiation and repression of global protein synthesis. This protein is thought to modulate mitochondrial function. It is a type I membrane protein located in the endoplasmic reticulum (ER), where it is induced by ER stress caused by malfolded proteins. Mutations in a similar gene in human are associated with Wolcott-Rallison syndrome. [provided by RefSeq, Sep 2015]
