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[1].
IC50 & Target

IC50: Elk-1[1]
体外研究
(In Vitro)

Elk-1 phosphorylation on Ser383/389 has a dual function and triggers both Elk-1 nuclear translocation and SRE-dependent gene expression[1].
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[1].
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[1].

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

Western Blot Analysis[2]

Cell Line: Neurons
Concentration: 5 μM; 10 μM
Incubation Time: 1 hour
Result: Decreased elk-1 expression and had no effects on ERK, MSK-1, or CREB phosphorylation.

RT-PCR[2]

Cell Line: Primary striatal neurons
Concentration: 5 μM
Incubation Time: 2 hour
Result: Decreased c-Fos, Zif268 and JunB mRNA level but did not effect c-Jun.
体内研究
(In Vivo)

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

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

Animal Model: C57Bl6 mice (3-6 months old males) are subjected to social defeat stress[2]
Dosage: 1 mg/kg
Administration: Intraperitoneal injection; daily; 14 days
Result: Reversed social-defeat induced decrease of hippocampal Bdnf expression by repeated TDE administration.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
