IREβ rabbit pAb - 100 μL

Catalytic activity: ATP + a protein = ADP + a phosphoprotein. Cofactor: Magnesium. enzyme regulation: The kinase domain is activated by trans-autophosphorylation. Kinase activity is required for activation of the endoribonuclease domain. function: Induces translational repression through 28S ribosomal RNA cleavage in response to ER stress. Pro-apoptotic. Appears to play no role in the unfolded-protein response, unlike closely related proteins. PTM: Autophosphorylated. similarity: Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. similarity: Contains 1 KEN domain. similarity: Contains 1 protein kinase domain.
