Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 PC-12 cells starved overnight and treated with β-NGF #5221 (50ng/ml) for 2h and either 10 μl of JunB (C37F9) Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR SimpleChIP® Rat CCRN4L Promoter Primers #7983, rat DCLK1 promoter primers, and SimpleChIP® Rat GAPDH Promoter Primers #7964. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.


JunB is a basic region, leucine zipper (bZIP) transcription factor belonging to the Jun family that includes c-Jun and JunD. 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蛋白是碱性亮氨酸拉链(bZIP)转录因子,属于Jun家族。该家族包括c-Jun 、JunD蛋白。Jun家族成员与Fos 、ATF蛋白形成同源二聚体或异源二聚体,构成功能性转录因子AP-1(活化蛋白1),它的活性由各种生理和病理刺激调节,如生长因子、传染病和应激性信号(1-4)。由于JunB 蛋白有时会拮抗c-Jun的转录活性,因此该蛋白在小鼠发育过程中可能是Jun蛋白的功能性替代物(5-7)。JunB 蛋白能调节造血干细胞数量,并在慢性粒细胞白血病 (CML)和急性髓细胞性白血病 (AML)的发病机理中发挥重要作用(8,9)。
