| 产品介绍 | CDCA2 is a regulator of chromosome structure during mitosis. CDCA2 forms an essential complex with protein phosphatase PP1-gamma subunit 1 (PPP1CC) and is required for the recruitment of PP1 to chromatin. Knockdown of CDCA2 by RNAi causes large-scale cell death by apoptosis, as does overexpression of a dominant-negative mutant of the protein. Function: Regulator of chromosome structure during mitosis required for condensin-depleted chromosomes to retain their compact architecture through anaphase. Acts by mediating the recruitment of phopsphatase PP1-gamma subunit (PPP1CC) to chromatin at anaphase and into the following interphase. At anaphase onset, its association with chromatin targets a pool of PPP1CC to dephosphorylate substrates. Subunit: Interacts with PPP1CC. Subcellular Location: Nucleus. Note=Excluded from the nucleolus. Present in nucleoplasm throughout the G1, S and G2 stages of the cell cycle. During M phase, it becomes diffuse throughout the cell as the nuclear membrane breaks down, and faintly accumulates later on metaphase chromatin. As the cell progresses to anaphase, it accumulates on chromatin. [ALTERNATIVE PRODUCTS] Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q69YH5-1; Sequence=Displayed; Name=2; IsoId=Q69YH5-2; Sequence=VSP_025598, VSP_025599; Note=No experimental confirmation available. Tissue Specificity: Ubiquitously expressed. Post-translational modifications: Phosphorylated by CDK1. May regulate its subcellular location.

文献和实验3 篇 Nature 连发,解决世纪难题,周期蛋白的毁灭调控蕴含癌症患者的新生
细胞周期是细胞生命活动的基本过程,受到细胞内外信号交互作用的精密调控。D 型细胞周期蛋白 (cyclin D1, D2 和 D3) 与细胞周期蛋白依赖性激酶(cyclin-dependent kinases,CDKs)是整个细胞周期调控机制中的核心分子,驱动细胞增殖。细胞周期失调是人类癌症的一个共同特征,其中 cyclin D-CDK4/6 复合物的水平和活性与不受约束的细胞增殖密切相关。自从 20 世纪 90 年代发现 cyclin D 以来,人们就对其进行了深入研究,但是关于 cyclin
Cdc2蛋白是裂殖酵母cdc2基因编码的蛋白,分子两34kDa,所以有称为p34cdc2 蛋白。通过对分离的裂殖酵母突变体的研究发现, 没有Cdc2的活性,细胞不能进入有丝分裂。这表明Cdc2是裂殖酵母进入有丝分裂的一个关键调节因子。实际上它是一种蛋白激酶,与周期蛋白结合后被激活,并促使细胞进入细胞周期。由于裂殖酵母中只有Cdc2一种蛋白激酶,所以p34cdc2 蛋白又被称为细胞周期引擎。
的作用。例如,组蛋白 H3N 端的磷酸化可能促进染色质在有丝分裂期间的凝集。在哺乳动物中,aurora B 是有丝分裂时 H3S10 磷酸化的激酶,但是在存在 aurora B 对 H3S10 的磷酸化是不够的。牛痘苗相关激酶 1 是哺乳动物 NHK1 的同系物,它能在体内和体外直接使组蛋白 H3T3 和 H3S10 磷酸化,而失去 VPK1 的活性,组蛋白 H3 的磷酸化也将减少。 组蛋白 H1 被细胞周期蛋白依赖的磷酸化是其翻译后主要的修饰作用。组蛋白 H1 的磷酸化能够影响 DNA 二级
