Specificity / Sensitivity

Acetylated-Lysine Antibody detects proteins posttranslationally modified by acetylation on the epsilon-amine groups of lysine residues. The antibody recognizes acetylated lysine in a wide range of sequence contexts. It has been demonstrated to recognize acetylated histones, p53, CBP, PCAF and chemically acetylated BSA. The antibody has been shown to react with as little as 0.04 ng of chemically acetylated BSA while not recognizing up to 25 µg of nonacetylated BSA. (U.S. Patent No's.: 6,441,140; 6,982,318; 7,259,022; 7,344,714; U.S.S.N. 11,484,485; and all foreign equivalents.)

Acetylation of lysine, like phosphorylation of serine, threonine or tyrosine, is an important reversible modification controlling protein activity. The conserved amino-terminal domains of the four core histones (H2A, H2B, H3, and H4) contain lysines that are acetylated by histone acetyltransferases (HATs) and deacetylated by histone deacetylases (HDACs) (1). Signaling resulting in acetylation/deacetylation of histones, transcription factors, and other proteins affects a diverse array of cellular processes including chromatin structure and gene activity, cell growth, differentiation, and apoptosis (2-6). Recent proteomic surveys suggest that acetylation of lysine residues may be a widespread and important form of posttranslational protein modification that affects thousands of proteins involved in control of cell cycle and metabolism, longevity, actin polymerization, and nuclear transport (7,8). The regulation of protein acetylation status is impaired in cancer and polyglutamine diseases (9), and HDACs have become promising targets for anti-cancer drugs currently in development (10).

赖氨酸的乙酰化如同丝氨酸、苏氨酸和酪氨酸的磷酸化一样,是一种控制蛋白活性的重要可逆手段。四个核心组蛋白(H2A, H2B, H3, H4)的保守氨基末端区域均包含赖氨酸,可以被组蛋白乙酰转移酶(HATs)乙酰化和组蛋白去乙酰酶(HDACs)去乙酰化(1)。组蛋白、转录因子和其它蛋白的乙酰化/去乙酰化信号最终影响多个细胞过程,包括染色体结构、基因活性、细胞生长、分化和凋亡等(2-6)。最近的蛋白组学研究显示赖氨酸残基的乙酰化是蛋白翻译后修饰的广泛而重要的手段,可以影响控制细胞周期、代谢、生存、肌动蛋白聚合和核转运相关的数千种蛋白。蛋白质乙酰化调节障碍在癌症和多聚谷氨酰胺疾病中发现(9),HDACs也成为目前正在开发的有希望的抗癌药物靶点(10)。
