General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |
||
About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Identification of the critical features of a small peptide inhibitor of JNK activity.[Pubmed:11790767]
J Biol Chem. 2002 Mar 29;277(13):10987-97.
The c-Jun N-terminal kinases (JNKs) are a subfamily of the mitogen-activated protein kinases (MAPKs). Although progress in evaluating the functions of other MAPKs has been facilitated by the characterization of specific inhibitors, no JNK-directed inhibitor is commercially available. We have identified a 21-amino acid peptide inhibitor of activated JNKs, based on amino acids 143-163 of the JNK-binding domain (JBD) of the JNK scaffolding protein, JNK-interacting protein-1 (JIP-1). This peptide, I-JIP (Inhibitor of JNK-based on JIP-1), inhibited JNK activity in vitro toward recombinant c-Jun, Elk, and ATF2 up to 90%. A truncated I-JIP (TI-JIP), the C-terminal 11 amino acids of I-JIP, directly interacted with recombinant JNKs but not its substrates as shown by surface plasmon resonance analysis. Scanning alanine replacement within truncated I-JIP identified 4 residues (Arg-156, Pro-157, Leu-160, or Leu-162) as independently critical for inhibition. JBD peptide sequences from JIP-2 and JIP-3 shared these critical residues and accordingly were effective JNK inhibitors. In contrast, peptides based on the JBDs of ATF2 and c-Jun inhibited JNK activity by <40%, which agreed with their lack of homology to the critical Arg-156 and Pro-157. These studies thus define a small peptide inhibitor sequence of JNKs based on the JIP proteins.
