Synthetic peptide corresponding to amino acids 339-354 of human JNK1 (c-Jun N-terminal kinase 1), conjugated to KLH. The sequence is highly conserved in JNK1, JNK2 α, β, γ (p54 SAPK α, β, γ) and identical in human, rat, and mouse JNK1.

General description

JNK (c-Jun N terminal protein kinase, also known as stress activated protein kinase, SAPK1) is a protein that belongs to serine/threonine-protein kinase family. It has a critical role in inhibiting WOX1 (WW domain-containing oxidoreductase) mediated apoptosis. It also mediates starvation-induced BCL2 phosphorylation and activates autophagy. Anti-c-Jun N-terminal kinase antibody can be used in microarray. Rabbit anti-c-Jun N-terminal kinase antibody reacts specifically with JNK1 (46 kD) and JNK2 (55 kD) of cell culture lysates and rat brain tissue extracts. The product has also shown weak cross reactivity for JNK2β (50 kD) isoform in mouse NIH-3T3 fibroblast cell lysate.


Anti-c-Jun N-terminal kinase antibody can be used in immunoblotting (diluted 1:16,000 or 1:2000) for detecting JNK1 (46kD) and JNK2 (55kD) isoforms using a rat brain extract and a NIH 3T3 mouse fibroblasts cell lysate.
