描述 概述 Recombinant, human PERK consisting of amino acids 563-1115 fused at the N-terminus to GST and expressed in E. coli. PERK phosphorylates the α-subunit of eukaryotic translation initiation factor 2 (EIF2α), which leads to its inactivation and reduces translation initiation. The active kinase is useful for the study of PERK regulation and for inhibitor screening. Note: the calculated MW is 88,000, but the protein runs at ~115,000 on SDS-PAGE. 产品目录编号 324881 品牌系列 Calbiochem®
