Description

MAPK9, also known as JNK2 (c-Jun N-terminal kinase 2), serves as a critical mediator of cellular stress responses and apoptotic signaling pathways. As a member of the stress-activated protein kinase family, MAPK9 phosphorylates key transcription factors including c-Jun, playing essential roles in inflammation, neurodegeneration, and cancer biology. Understanding MAPK9 activation and localization provides valuable insights into how cells respond to environmental stressors, cytokines, and growth factor withdrawal.

This recombinant monoclonal antibody, clone 3F10, offers the reproducibility and consistency that demanding research applications require. Generated against a synthetic peptide derived from human MAPK9 and produced using recombinant technology in rabbit host, this antibody delivers sequence-defined specificity with minimal lot-to-lot variation. The affinity-chromatography purification ensures high purity, while the unconjugated format provides flexibility for pairing with your preferred secondary detection systems.

Validation studies demonstrate reliable performance in both immunofluorescence and flow cytometry applications using human samples. Immunofluorescence staining of MCF-7 breast cancer cells reveals clear MAPK9 detection when used at dilutions between 1:50 and 1:200, with the signal distinctly visualized against DAPI nuclear counterstaining. Flow cytometry analysis of the same cell line confirms specific detection, with overlay histograms showing clear separation between antibody-stained populations and isotype control samples at 1:100 dilution.

This antibody supports researchers investigating stress-activated kinase signaling, apoptosis regulation, and inflammatory responses. Its validated performance in cell-based assays makes it particularly suitable for studies examining MAPK9 expression patterns, subcellular localization, and population-level protein expression analysis in human cell models.

Target Background

Function

Serine/threonine-protein kinase involved in various processes such as cell proliferation, differentiation, migration, transformation and programmed cell death. Extracellular stimuli such as proinflammatory cytokines or physical stress stimulate the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling pathway. In this cascade, two dual specificity kinases MAP2K4/MKK4 and MAP2K7/MKK7 phosphorylate and activate MAPK9/JNK2. In turn, MAPK9/JNK2 phosphorylates a number of transcription factors, primarily components of AP-1 such as JUN and ATF2 and thus regulates AP-1 transcriptional activity. In response to oxidative or ribotoxic stresses, inhibits rRNA synthesis by phosphorylating and inactivating the RNA polymerase 1-specific transcription initiation factor RRN3. Promotes stressed cell apoptosis by phosphorylating key regulatory factors including TP53 and YAP1. In T-cells, MAPK8 and MAPK9 are required for polarized differentiation of T-helper cells into Th1 cells. Upon T-cell receptor (TCR) stimulation, is activated by CARMA1, BCL10, MAP2K7 and MAP3K7/TAK1 to regulate JUN protein levels. Plays an important role in the osmotic stress-induced epithelial tight-junctions disruption. When activated, promotes beta-catenin/CTNNB1 degradation and inhibits the canonical Wnt signaling pathway. Participates also in neurite growth in spiral ganglion neurons. Phosphorylates the CLOCK-ARNTL/BMAL1 heterodimer and plays a role in the regulation of the circadian clock. Phosphorylates POU5F1, which results in the inhibition of POU5F1's transcriptional activity and enhances its proteosomal degradation.; MAPK9 isoforms display different binding patterns: alpha-1 and alpha-2 preferentially bind to JUN, whereas beta-1 and beta-2 bind to ATF2. However, there is no correlation between binding and phosphorylation, which is achieved at about the same efficiency by all isoforms. JUNB is not a substrate for JNK2 alpha-2, and JUND binds only weakly to it.
