Confocal immunofluorescent analysis of Jurkat (positive; left) and HeLa (negative; right) cells using Bcl-11B (D6F1) XP® Rabbit mAb (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

使用Bcl-11B (D6F1) XP®Rabbit mAb(绿色)对Jurkat(阳性;左)和HeLa(阴性;右)细胞进行激光共聚焦免疫荧光分析。肌动蛋白丝使用DY-554 phalloidin 标记(红色)。蓝色伪彩= DRAQ5® #4084 (DNA荧光染色)。

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 Jurkat cells and either 10 μl of Bcl-11B (D6F1) XP® 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 using SimpleChIP® Human CDKN1B Promoter Primers #11951, human MDM2 promoter primers, and SimpleChIP® Human α Satellite Repeat Primers #4486. 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.

使用SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003中的10 μl Bcl-11B (D6F1) XP® Rabbit mAb兔单抗或2 μl Normal Rabbit IgG #2729与4 x 106 Jurkat交联后进行进行染色质免疫共沉淀实验。富集的DNA使用SimpleChIP® Human CDKN1B Promoter 引物 #11951, human MDM2 引物, 和SimpleChIP® Human α Satellite Repeat 引物 #4486进行实时荧光定量PCR实验。各样品沉淀得到的DNA量比对input染色质总量进行定量,Input染色质量设定值为1。

Bcl-11B (Ctip2) is a COUP-TF interacting protein that belongs to the C2H2 type zinc finger protein family (1). Bcl-11B is highly expressed in the brain and is critical for the development of neurons, as well as other tissues and organs. Bcl-11B also plays an essential role in T cell lineage commitment and maintenance of T cell identity (1-3). Two isoforms of Bcl-11B are found to be encoded by the BCL11B gene, possibly through exon-skipping (4). Bcl-11B is a transcription factor which binds to target genes through the 2nd and 3rd zinc-finger domains of exon 4 (3), while also interacting with various protein partners including COUP-TF proteins (1), the NuRD complex (5,6), HDAC1, HDAC2, and SUV39H1 (7). Research studies have shown that mutations and deletion of Bcl-11B contribute to the development of thymic lymphoma in mice and T cell acute lymphoblastic leukemia in humans, indicating a role as a tumor suppressor (4,8). Mechanistic studies have shown that Bcl-11B represses gene expression of the E3 ubiquitin ligase HDM2 in a p53-dependent manner (9).

Bcl-11B (Ctip2)是一个COUP-TF作用蛋白,属于C2H2型锌指蛋白家族(1)。Bcl-11B在大脑中高表达,对于神经和其他组织和器官的发育是必须的。 Bcl-11B在T细胞系的功能和维护T细胞身份也扮演重要角色(1-3)。BCL11B 基因可能通过外显子的不同转录编码了BCL-11B的两种异构型蛋白。BCL-11B是一类通过其第4外显子(3)中第二和第三锌指结构域结合靶向基因的转录因子,同时也与包括COUP-TF proteins (1), the NuRD complex (5,6), HDAC1, HDAC2和 SUV39H1 (7)等多种蛋白伴侣相互作用。 已有研究发现Bcl-11B突变和丢失会导致小鼠的胸腺肿瘤的发生和人类的T细胞急性粒细胞白血病,显示其抑癌基因的角色(4,8)。研究机制发现Bcl-11B非依赖于P53 的抑制E3泛素连接酶HDM2的基因表达(9)。
