Jun family members homodimerize or heterodimerize with Fos and ATF proteins to form a functional transcription factor AP-1 (activator protein 1), whose activity is regulated by a variety of physiological and pathological stimuli such as growth factors, infections, and stress signals (1-4). While JunB sometimes antagonizes c-Jun transcriptional activity, it may functionally substitute for c-Jun during development in mice (5-7). JunB regulates hematopoietic stem cell number and plays an important role in the pathogenesis of chronic myelogenous leukemia (CML) and acute myeloid leukemia (AML) (8,9). JunB expression is selectively induced in T helper 2 (Th2) cells during T cell differentiation. JunB interacts with c-Maf, and the resulting complex functions synergistically to activate transcription of Interleukin-4 (IL-4), one of the signature cytokines secreted by Th2 cells. Transcriptional regulation of IL-4 was shown to be enhanced by JNK-mediated phosphorylation of JunB at Thr102 and Thr104 (10). Phosphorylation of these residues enhances DNA binding of the JunB\/c-Maf complex at the P1 regulatory site of the IL-4 promoter, leading to Th2-restricted IL-4 expression.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nactivator protein 1; AP-1; jun B proto-oncogene; JUNB; JunB proto-oncogene, AP-1 transcription factor subunit; Transcription factor jun-B; Transcription factor JunB\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 43\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799916433577,"sku":"8053T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-8053t","provider":"Iright","version":"1.0","type":"link"}
