The adaptor protein ARA55 and the nuclear kinase HIPK1
2017年7月1日 · Androgen receptor-associated protein 55 (ARA55) belongs to this family of bridging proteins containing four C-terminal LIM domains. It has a dual role with functions both at focal adhesions and in the nucleus, apparently shuttling between the two compartments.
衰老上调基质细胞中的ARA55,诱导雄激素介导的前列腺癌细胞的 …
由于ar经验在pz老细胞和pz年轻细胞中是等效的,因此我们集中研究了雄激素受体相关蛋白55(ara55),一种基质特异性雄激素受体(ar)共激活剂。 与体外的PZ年轻细胞相比,PZ老细胞中的ARA55表达更高。
Cloning and characterization of androgen receptor coactivator, ARA55 …
1999年3月19日 · We report here the cloning of a novel AR coactivator ARA55 using a yeast two-hybrid system. ARA55 consists of 444 amino acids with the predicted molecular mass of 55 kDa and its sequence shows very high homology to mouse hic5, a TGF-beta1-inducible gene.
Cloning and Characterization of Androgen Receptor Coactivator, ARA55 ...
1999年3月19日 · Here we report for the isolation and characterization of a novel AR coactivator, ARA55, which can bind to wild type AR (wtAR) and mutant AR (mAR) in a ligand-dependent manner and enhance their transcriptional activities. The potential roles of ARA55 in prostate cancer is also discussed.

Hic-5/ARA55蛋白的研究进展 - 百度学术
Hic-5/ARA55基因最早是作为转化生长因子β1诱导基因 (TGF-β1)和过氧化氢 诱导的克隆从小鼠成骨细胞MC3T3中分离出来,属于LIM结构域蛋白家族,与桩蛋白具有高度同源性.Hic-5/ARA55蛋白主要位于细胞黏着斑,可 以穿梭于细胞质和细胞核的蛋白质. 百度学术集成海量学术资源,融合人工智能、深度学习、大数据分析等技术,为科研工作者提供全面快捷的学术服务。 在这里我们保持学习的态度,不忘初心,砥砺前行。
ARA55过表达激活内源性线粒体凋亡通路诱导CNE2鼻咽癌细胞凋 …
研究显示,ARA55 可能 是一种抑癌基因,因其在部分恶性肿瘤包括前列腺 癌 、胰 腺 癌 以 及 食 管 鳞 癌 等 的 癌 组 织 表 达 明 显 降 低,而在相应的癌旁组织中表达升高[3-5]。 然而有研 究发现 ARA55 在癌细胞发生侵袭转移时的形态改 变 及 可 塑 性 等 过 程 中 发 挥 重 要 作 用[6]。 目 前 , ARA55 在鼻咽癌的发生与发展中发挥的作用尚不 明确。 本研究拟探讨 ARA55 基因/ 蛋白表达上调对 CNE2 鼻咽癌生长增殖和侵袭迁移等生物学特性的 影响,同时探讨相应的分子机制, …
We report here the cloning of a novel AR coactiva-tor ARA55 using a yeast two-hybrid system. ARA55 con-sists of 444 amino acids with the predicted molecular mass of 55 kDa and its sequence shows very high homol-ogy to mouse hic5, a TGF-b1-inducible gene.
Inactivation of androgen receptor coregulator ARA55 inhibits …
2003年4月29日 · Here, we report that expression of a dominant-negative AR-associated protein 55 (dARA55) coregulator, inhibits AR transcriptional activity and reduces the agonist activity of antiandrogens. Inducibly expressed dARA55 inhibits prostate-specific antigen and cell growth in prostate cancer cells.
The adaptor protein ARA55 and the nuclear kinase HIPK1
2017年7月1日 · We propose that ARA55 and HIPK1 assist c-Myb in recruiting p300 to chromatin. LIM-domain proteins, containing multiple cysteine-rich zinc finger-like motifs, have been shown to play diverse roles in several cellular processes. A common theme is that they mediate important protein-protein interactions that are key to their function.
