乙酸 豆塞外 佛波酯 (12-o-tertradecanoylphordol-13-acetate, TPA;或phorbol-12-myristate-13-acetate,PMA)是一种促 肿瘤 剂,由于基结构与DAG相似,可在很低浓度下模拟DAG,活化PKC,使PKC亲和力增至10-7M。PKC是TPA的受体,当TPA插入细胞膜后可以替代DAG而直接活 …
PKD at the crossroads of DAG and PKC signaling - PubMed
DAG regulates the intracellular localization of PKD and also activates PKD through PKC by phosphorylation. The PKC-PKD signaling cascade is crucial to PKD function in cells. Important discoveries have been made regarding the roles of PKD in cell growth, gene expression, survival, motility, protein trafficking and lymphocyte biology.
壹生资讯-糖尿病大血管病变发病机制——蛋白激酶C(PKC)途径
2021年1月31日 · dag是机体内主要的pkc激动剂。生理情况下,dag主要来源于磷酸肌醇的代谢和磷脂酰胆碱的裂解,但也可由脂质 前体 在磷脂酶a2的作用下释放出游离脂肪酸而生成。高血糖激活pkc信号通路主要通过dag途径。
Diacylglycerol-evoked activation of PKC and PKD isoforms in …
2020年5月28日 · Protein kinase C (PKC) and Protein kinase D (PKD) isoforms can sense diacylglycerol (DAG) generated in the different cellular compartments in various physiological processes. DAG accumulates in multiple organs of the obese subjects, which leads to the disruption of metabolic homeostasis and the development of diabetes as well as associated ...

Protein kinase C and beyond - Nature Immunology
2004年7月28日 · DAG binds to conserved C1 domains in many different molecules, including various isoforms of PKC, PKD, Ras-GRP (activators of the GTPase Ras) and DGK (which phosphorylates DAG to produce ...
PKD at the crossroads of DAG and PKC signaling - ScienceDirect
2006年6月1日 · Protein kinase D (PKD), a novel DAG receptor, has been the subject of intense investigation in recent years. DAG regulates the intracellular localization of PKD and also activates PKD through PKC by phosphorylation. The PKC–PKD signaling cascade is crucial to PKD function in cells.
PKC 通路 | Cell Signaling Technology
蛋白激酶 c (pkc) 家族成员调控大量的细胞反应,包括基因表达、蛋白分泌、细胞增殖和炎性反应。其基本的蛋白结构包括一个 n 端调节区,该调节区由一个铰链区连接至 c 端激酶区域。
Novel Features of DAG-Activated PKC Isozymes Reveal a …
2016年1月16日 · Diacylglycerol (DAG) activates the eight conventional and novel isozymes of protein kinase C (PKC) by binding to their C1 domains. The crystal structure of PKCβII in a partially activated conformation showed how the C1B domain regulates activity by clamping a helix in the C-terminal AGC extension of the kinase domain.
对G蛋白介导的信号通路的理解 - 知乎 - 知乎专栏
激素作用于G蛋白偶联受体,使得G蛋白释放Gα亚基,Gα亚基激活 磷脂酶C,活化的磷脂酶C催化PIP2水解生成 IP3 和DAG两个第二信使。 而后IP3和DAG又参与两个不同的信号通路。 其中,IP3- Ca2+ 信号通路由PIP2水解产生的IP3经细胞内扩散,到达内质网膜,结合在内质网膜上的IP3敏感的Ca2+通道上,并使得Ca2+通道打开,引发Ca2+从内质网腔的Ca2+库中释放到细胞质基质中,到达细胞质基质的Ca2+与 钙调蛋白 结合,进而引起细胞反应。 其中,DAG-PKC信号通路.
