The antibody has been shown to recognize the endogenous, active forms of JNK 1 + 2 in a variety of cell types following treatment by a broad range of extracellular stimuli [e.g. including 293 cells (human embryonic kidney; +\/- ultraviolet light) and PC12 cells (rat pheochromocytoma; +\/- sorbital)]. The region of JNK1 and JNK2 surrounding T183 + Y185 has a high degree of similarity to the corresponding regions in JNK3 and thus may cross react with this protein if phosphorylated on the corresponding residues.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nForm-Liquid, Purification technique-Affinity purification Immunogen, Purification notes-Purified from rabbit serum by sequential epitope specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated JNK enzymes. The final product is generated by affinity chromatography using a JNK-derived peptide that is phosphorylated at threonine 183 and tyrosine 185, within the activation loop.

These proteins are serine\/threonine kinases with a known molecular weight around 46-54 kDa depending on their phosphorylation state. JNK1 and JNK2 phosphorylate specific target proteins which include transcription factors and other kinases to regulate various cellular processes. They are expressed in most tissues with higher levels in brain heart and skeletal muscle. JNK isoforms have become essential in research involving stress responses where specific tools such as JNK antibodies and Western blot assays targeting p-JNK molecular weight are critical for study.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThese enzymes play vital roles in regulating cellular responses to stress stimuli. JNK1 and JNK2 form part of larger signaling complexes including the JNK molecular weight complex that is activated in stressful conditions like UV radiation or cytokines. Once activated they phosphorylate transcription factors such as c-Jun leading to gene expression changes that facilitate adaptative and survival responses. They modulate cellular processes like apoptosis inflammation and cell differentiation clearly contributing to homeostasis and development.\u003cbr\u003e\nPathways\u003cbr\u003e\nThese kinases interact significantly within the MAPK (Mitogen-activated protein kinase) and apoptosis pathways. JNK proteins mediate signals from upstream kinases such as MKK4\/7 and respond to inflammatory cytokines resulting in transcriptional alterations. Their downstream impact is tightly linked to apoptosis through interactions with Bcl-2 family members affecting cellular fate. ERK and p38 MAPK proteins closely interact with JNK pathways co-regulating cellular stress responses and survival pathways highlighting their importance in maintaining cellular balance.\u003cbr\u003e\nThe altered regulation of JNK1 and JNK2 links them to diverse conditions such as cancer and neurodegenerative diseases. In cancer abnormal JNK activity affects cell proliferation and apoptosis with JNK pathways often hyperactivated in tumors. In neurodegeneration these kinases contribute to cell death as seen in disorders like Alzheimer's disease where they engage with proteins like tau leading to neuronal apoptosis. The connection of JNK proteins to other stress-activated kinases further positions them as critical therapeutic targets in disease modulation.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845022961833,"sku":"ab4821","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab4821","provider":"Iright","version":"1.0","type":"link"}
