This antibody detects endogenous levels of JNK1/JNK2 only when phosphorylated at Thr183/Tyr185.
Aufreinigung
Immunoaffinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Immunogen
The antiserum was produced against synthesized phosphopeptide derived from human JNK1/JNK2 around the phosphorylation site of Thr183/Tyr185 (M-M-Tp-P-YP-V-V).
Western blot: 1/500approx. 1/1000. Immunofluorescence: 1/100approx. 1/200. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Target
JNK (MAPK8)
(Mitogen-Activated Protein Kinase 8 (MAPK8))
JNK (c-Jun N-terminal Kinase), also referred to as Stress Activated Protein Kinase (SAPK), is one of the main mitogen-activated protein kinases (MAPKs) in mammals. JNK is expressed as ten different isoforms due to differential mRNA splicing. The predominant forms are JNK1 and JNK2. JNK is activated by a variety of cellular signals including growth factors, inflammatory cytokines, and environmental stress. The JNK/SAPK signaling pathway involves sequential activation of MAPK kinase kinase (MEKK1), MAPK kinase 4 (MKK4) or MKK7, SAPK/JNK, and c-Jun. Full activation of JNK requires phosphorylation of a threonine and a tyrosine residue in the motif Thr-Pro-Tyr. MKK7 and MKK4 phosphorylate JNK at threonine 183 and tyrosine 185, respectively. The JNK pathway functions to modulate cell cycle, apoptotic and transcriptional responses to stress.Synonyms: JNK-46, JNK-55, JNK1/JNK2, MAPK8, MAPK9, PRKM8, PRKM9, SAPK1, c-Jun N-terminal kinase 1, c-Jun N-terminal kinase 2
