| Specificity / Sensitivity | Acetyl-CBP (Lys1535)/p300 (Lys1499) Antibody detects endogenous levels of CBP or p300 only when acetylated at lysine 1535 or lysine 1499, respectively. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic acetylated peptide corresponding to residues surrounding Lys1535 of human CBP. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from A431, NIH/3T3, COS and PC12 cells, using Acetyl-CBP (Lys1535)/p300 (Lys1499) Antibody. Western Blotting
Western blot analysis of hypo- or hyper-acetylated recombinant p300 HAT domains, either wild-type or K1499R mutant, using Acetyl-CBP (Lys1535)/p300 (Lys1499) Antibody (upper). Also shown in the corresponding coomassie stained SDS-PAGE gel (lower). (Details are described in Thompson, P.A. et al. (2004) Nat. Struct. Mol. Biol. 11, 308-315.) Chromatin IP
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 293 cells treated with Forskolin #3828 (30uM) and either 20 μl of Acetyl-CBP (Lys1535)/p300 (Lys1499) Antibody 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 human ALS2 exon 1 primers, SimpleChIP® Human NR4A3 Promoter Primers #4829, 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. |
| Background | CBP (CREB-binding protein) and p300 are highly conserved and functionally related transcriptional co-activators that associate with transcriptional regulators and signaling molecules, integrating multiple signal transduction pathways with the transcriptional machinery (1,2). CBP/p300 also contain histone acetyltransferase (HAT) activity, allowing them to acetylate histones and other proteins (2). Phosphorylation of p300 at Ser89 by PKC represses its transciptional acitivity, and phosphorylation at the same site by AMPK disrupts the association of p300 with nuclear receptors (3,4). Ser1834 phosphorylation of p300 by Akt disrupts its association with C/EBPβ (5). Growth factors induce phosphorylation of CBP at Ser437, which is required for CBP recruitment to the transcription complex (6). CaM kinase IV phosphorylates CBP at Ser302, which is required for CBP-dependent transcriptional activation in the CNS (7). The role of acetylation of CBP/p300 is of particular interest (2,8). Acetylation of p300 at Lys1499 has been demonstrated to enhance its HAT activity and affect a wide variety of signaling events (9).

文献和实验于基因转录。 迄今为止，已鉴定的人HAT可分为以下五大类 (1)Gcn5相关N―乙酰基转移酶(GNAT)超家族：GNAT超家族成员在几个同源区域和乙酰化相关基序存在相似性。决定该超家族的4个序列基序C、D、A、B的功能尚未完全阐明。基序C仅存在于GNAT家族的大多数HAT中，而基序A则高度保守，也存在于其他HAT家族，如MYST家族。另外，该家族还包含一个Arg／Gin―X―X―Gly―X―Gly／Ala片段，主要功能为特异性乙酰CoA底物的识别和结合。 (2)P300／CBP
【求助】P53的翻译后修饰都有哪些？ 怎样验证其修饰后与靶标启动子的结合活性的变化？
化，如Ser313、Ser314、Thr377、Ser378(被CHK1 ,CHK2磷酸化)、Ser366 (只被CHK2磷酸化)、Thr387 (只被CHK1磷酸化)。这些位点的磷酸化可能会改变 Lys373、Lys382乙酰化的方式，但不会改变Lys320，因此可以用来区分P300/CREB结合蛋白（CBP）和P300/CBP 相关因子(PCAF)活性[20].。 当大多数p53的磷酸化可以增强蛋白质的稳定性和活性时，一些位点的磷酸化（Thr55 、Thr155 、Ser205
，为此CST公司推出了可用于蛋白功能检测的乙酰化组蛋白系列抗体,圆满的解决这个问题。因为乙酰化与蛋白的活性相关，因此通过乙酰化的系列抗体特异性地识别靶蛋白的乙酰化形式，可以反映出靶蛋白质的活性水平，达到研究蛋白功能和调节的目的。而其他的抗体仅能反映出该蛋白质的表达量或表达水平，不能反映出蛋白的活性状态。乙酰化系列抗体：Catalog#Product DescriptionSourceApplications2576Acetyl-Histone H2A (Lys5) AntibodyRabbitW IP
