Interaction Information:

Comment The pancreatic ER kinase or PKR-like kinase (PERK) is an ER transmembrane protein kinase that phosphorylates the alpha subunit of translation initiation factor 2 (eIF2-alpha) in response to ER stress. The phosphorylation status of PERK and eIF2-alpha is therefore a key indicator of the presence of ER stress. Determination of the phosphorylation status demonstrated increased PERK and eIF2-alpha phosphorylation in liver extracts of obese mice compared with lean controls. As in liver, PERK phosphorylation was significantly increased in adipose tissue.

Comment Alterations in the levels of cellular XBP-1s protein, the spliced or processed form of XBP-1, result in alterations in the ER stress responses.
