PERK Antibody (MA5-51928) in WB
Western blot was performed using PERK Rabbit Recombinant Monoclonal Antibody (PSH0-81) (Product # MA5-51928) and 140 kDa band corresponding to PERK was observed across cell lines tested. Whole cell extracts (20 µg lysate) of MCF7 (Lane 1), HepG2 (Lane 2), HEK-293 (Lane 3), HeLa (Lane 4), A549 (Lane 5), U-87 MG (Lane 6), and whole cell extracts (16 µg lysate) of K-562 (Lane 7) were electrophoresed using 4-20% SDS-PAGE gel. Resolved proteins were transferred onto a PVDF membrane. The blot was blocked with 5% NFDM/TBST for 1 hour at room temp... View More

Target Information
EIF2AK3 (PERK) is one of 4 kinases that specifically phosphorylate Ser51 of translation initiation factor eIF2-alpha in response to various environmental stresses, leading to a decrease in protein sythesis. In the case of EIF2AK3, signaling is initiated by misfolded proteins in the ER. Defects in EIF2AK3 are the cause of Wolcott-Rallison syndrome (WRS), also known as multiple epiphyseal dysplasia with early-onset diabetes mellitus. WRS is a rare autosomal recessive disorder, characterized by permanent neonatal or early infancy insulin-dependent diabetes and, at a later age, epiphyseal dysplasia, osteoporosis, growth retardation and other multisystem manifestations, such as hepatic and renal dysfunctions, mental retardation and cardiovascular abnormalities.
