Descripción

General description

A cell-permeable 37 amino acid peptide constructed by fusing the JNK binding domain sequence (δ) (amino acids 33-57) of human c-Jun to the HIV-TAT transduction domain sequence (amino acids 47-57) with a γ-aminobutyric acid (GABA) spacer. Reported to specifically disrupt c-Jun/JNK complex formation and subsequent phosphorylation and activation of c-Jun by JNK in vitro and in intact cells. Also reported to induce apoptosis in HeLa cells. Mode of inhibition is distinct from that of JNK Inhibitor II (SP600125; Cat. No. 420119), so may complement this inhibitor in JNK pathway studies.

A cell-permeable 37-mer peptide constructed by fusing human c-Jun δ domain (amino acids 33-57) sequence with that of HIV-TAT protein transduction domain (amino acids 47-57) via a γ-aminobutyric acid (GABA) spacer. Shown to specifically disrupt c-Jun/JNK complex formation and the subsequent phosphorylation and activation of c-Jun by JNK both in vitro and in intact cells. Since its mode of inhibition is different than that of JNK Inhibitor II (SP600125; Cat. No. 420119), these two inhibitors can complement each other in JNK signaling pathway studies.
