TAT-DEF-Elk-1 TDE

产品介绍

TAT-DEF-Elk-1 (TDE) 是 Elk-1 的一种可穿透细胞的肽抑制剂，通过模仿和特异性干扰 Elk-1 的 DEF 结构域来实现抑制。TAT-DEF-Elk-1 阻止 Elk-1 磷酸化并防止 Elk-1 核易位，且不会干扰 ERK 或 MSK1 活化。TAT-DEF-Elk-1 是分析神经元可塑性发展过程中 Elk-1 在此过程中的作用的有用工具。

生物活性

TAT-DEF-Elk-1 (TDE) is a cell-penetrating peptide inhibitor of Elk-1, mimics and specifically interferes with the DEF domain of Elk-1. TAT-DEF-Elk-1 blocks Elk-1 phosphorylation and prevents Elk-1 nuclear translocation without interfering with ERK nor MSK1 activation. TAT-DEF-Elk-1 is a useful tool to analyze the role of Elk-1 in this process during the development of neuronal plasticity.

体外研究

Elk-1 phosphorylation on Ser383/389 has a dual function and triggers both Elk-1 nuclear translocation and SRE-dependent gene expression.
TAT-DEF-Elk-1 (5-10 μM; 1 hour) specifically inhibits glutamate-induced elk-1 activation and does not interfer with ERK, MSK-1, or CREB phosphorylation.
TAT-DEF-Elk-1 (5 μM; 2 hour) treatment shows a significant inhibition of c-Fos, Zif268 and JunB, but has no effects on c-Jun expression.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis

体内研究
(In Vivo)

TAT-DEF-Elk-1 (intraperitoneal injection; 1mg/kg; daily; 14 days) reflects antidepressant efficacy in mice, it decreases immobility similar to the reference antidepressants fluoxetine and desipramine (DMI).
