Overview:
JNK2 and JNK3 are members of the c-Jun N-terminal kinases (JNKs) which are part of the mitogen-activated protein (MAP) kinase family, and regulate signal transduction in response to environmental stress. JNK2 binds to the c-Jun transactivation domain and phosphorylates it on Ser-63 and Ser-73 (1). JNK2 has been shown to play an important role in disease processes. JNK2 plays a role in ventricular hypertrophy and is thought to be involved in hypertensive cardiac disease (2). JNK3 phosphorylates various transcription factors such as ATF2, Elk-1 and members of the Jun family (3). Activation and nuclear localization of JNK3, a neuronal-specific isoform of JNK, has been associated with hypoxic and ischemic damage of CA1 neurons in the hippocampus. Knockout mice lacking JNK3 showed reduced apoptosis of hippocampal neurons and reduced seizure induced by kainic acid, a glutamate-receptor agonist (4).

Specificity:
Recognizes JNK2 and JNK3 protein
Cross Reactivity:
Western blot of human JNK2 and JNK3
ERK1 from other species may also be detectable.
Host:
Rabbit
Immunogen:
C-terminal peptide of JNK3 conjugated to ovalbumin
Purification:
Affinity chromatography
Stability:
Store at 4°C (add 0.1% NaN3) for several months, and at -20°C for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For optimal performance, avoid repeated handling and multiple freeze/thaw cycles.
