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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Antigen affinity purified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePredicted species reactivity:\u003c\/strong\u003e Chicken, Mouse\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NSJ Bioreagents","offers":[{"title":"In 1X PBS, pH 7.4, with 0.09% sodium azide \/ 0.05 ml","offer_id":53042934874477,"sku":"F53948-0.05ML","price":205.0,"currency_code":"USD","in_stock":true},{"title":"In 1X PBS, pH 7.4, with 0.09% sodium azide \/ 0.2 ml","offer_id":53043014893933,"sku":"F53948-0.2ML","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_ba99f5da-9b05-4e18-9af7-6b79cfb4551f.jpg?v=1771924032","url":"https:\/\/www.ebiohippo.com\/products\/phospho-jnk-sapk-antibody-pthr183-tyr185-bha17102554","provider":"BioHippo","version":"1.0","type":"link"}
