背景信息

The SAPK/JNK (Stress-activated protein kinase/c-Jun N-terminal kinase) family, part of the MAPK (mitogen-activated protein kinase) signaling pathway, plays a critical role in cellular responses to stress, apoptosis, inflammation, and differentiation. JNKs are activated by dual phosphorylation at conserved threonine (Thr183) and tyrosine (Tyr185) residues within their activation loop, mediated by upstream kinases like MKK4/7. Phosphorylation at these sites induces conformational changes, enabling JNK to phosphorylate substrates such as c-Jun, ATF2. and other transcription factors.

The SAPK/JNK (Phospho-Thr183) antibody specifically detects JNK phosphorylated at Thr183. serving as a key tool to study JNK activation status in signaling research. This antibody is widely used in techniques like Western blotting, immunofluorescence, and immunohistochemistry to assess JNK pathway activity under stress conditions (e.g., UV radiation, cytokines, oxidative stress) or in disease models (e.g., cancer, neurodegenerative disorders).

Three major isoforms (JNK1. JNK2. JNK3) exist, with JNK1/2 ubiquitously expressed and JNK3 predominantly in the brain. Dysregulated JNK signaling is linked to pathologies, including inflammation and apoptosis-related diseases. The Phospho-Thr183 antibody helps elucidate JNK's role in these processes, aiding therapeutic target discovery. Proper controls (e.g., total JNK antibodies, kinase inhibition) are essential to validate phosphorylation-specific results and avoid cross-reactivity with related kinases.
