基本信息
| Empirical Formula【经验(实验)分子式】 | C136H241N53O31S |
| Molecular weight | 3146.77 |
| General description【一般描述】 | A cell-permeable and reversible 13-amino acid peptide corresponding to the N-terminus of MAPK/ERK kinase (MEK or MAPKK) that is fused to the HIV-TAT membrane translocation peptide (MTP) sequence via a glycine linker. Acts as a specific inhibitor of ERK activation by MEK1 and the downstream transcriptional activity of ELK1. Selectively binds to ERK2 and prevents its interaction with MEK (IC50 = 210 nM in vitro). Potently blocks ERK in PMA-stimulated NIH3T3 cells and NGF-treated PC12 cells (IC50 = 29 µM). Does not inhibit the activation of c-jun N-terminal kinases (JNKs) or p38 MAP kinase. A cell-permeable and reversible 13-amino acid peptide corresponding to the N-terminus of MEK1 (MAPKK) that is fused to the HIV-TAT membrane translocating peptide (MTP) sequence via a glycine linker. Acts as a specific inhibitor of ERK activation and blocks the transcriptional activity of Elk1. Selectively binds to ERK2 and prevents its interaction with MEK (IC50 = 210 nM). Potently blocks ERK activation in PMA-stimulated NIH 3T3 cells and NGF-treated PC12 cells (IC50 = 29 µM). Does not affect the activation of JNKs or p38. |
