生物活性 | TAT-DEF-Elk-1 TFA (TDE TFA) is a cell-penetrating peptide inhibitor of Elk-1, mimics and specifically interferes with the DEF domain of Elk-1. TAT-DEF-Elk-1 TFA blocks Elk-1 phosphorylation and prevents Elk-1 nuclear translocation without interfering with ERK nor MSK1 activation. TAT-DEF-Elk-1 TFA 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 TFA (5 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 TFA (5-10 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.
