Gene

PEK

Species
Drosophila melanogaster
Symbol
PEK
Name
pancreatic eIF-2alpha kinase
Synonyms
  • CG2087
  • DmPEK
Biotype
protein coding gene
Automated Description
Enables eukaryotic translation initiation factor 2alpha kinase activity. Involved in several processes, including PERK-mediated unfolded protein response; positive regulation of JNK cascade; and regulation of G2/M transition of mitotic cell cycle. Is active in endoplasmic reticulum. Is expressed in several structures, including adult head; larval muscle cell; larval muscle system; and trunk visceral muscle primordium. Human ortholog(s) of this gene implicated in Wolcott-Rallison syndrome and type 1 diabetes mellitus. Orthologous to human EIF2AK3 (eukaryotic translation initiation factor 2 alpha kinase 3).
FB Description
pancreatic eIF-2alpha kinase (PEK) encodes an endoplasmic reticulum (ER) transmembrane kinase and a component of the integrated stress response. During ER stress the product of PEK phosphorylates the translation initiation factor encoded by eIF2alpha resulting in the inhibition of most cap-dependent translation. This is especially important during the development of secretory tissues and the response to cellular stress.
