설명

일반 설명

A cell-permeable, biologically active peptide consisting of a carboxyl terminal sequence derived from the JNK-binding domain (JBD) and an amino terminal peptide containing the HIV-TAT_48-57 sequence. Blocks c-Jun NH₂-terminal kinase (JNK) signaling by preventing the activation of the transcription factor c-jun (IC₅₀ ~ 1 µM). This effect appears to be due to inhibition of phosphorylation of the activation domains of JNK. Contains the minimal 20-amino acid inhibitory domain of islet-brain (IB) that is shown to be critical for interaction with JNK linked to the 10-amino acid HIV-TAT_48-57 sequence as a carrier peptide and two proline residues as spacer. Inhibits IL-1β-induced c-jun and c-fos expression in insulin secreting βTC-3 cells and offers protection against apoptosis. Does not affect insulin secretion and has no effect on either ERK 1/2 or p38 activities.

Blocks the activation domain of c-Jun NH₂-terminal kinase (JNK) and prevents the activation of the transcription factor c-Jun (IC₅₀ ~1 µM). Contains the minimal 20-amino acid inhibitory domain of islet-brain (IB), which is critical for interaction with JNK.The peptide is covalently linked to the 10-amino acid HIV-TAT_48-57 sequence that acts as a carrier peptide and to two proline residue spacers. Inhibits IL-1β-induced c-Jun and c-fos expression in insulin secreting βTC-3 cells and offers protection against apoptosis. Does not affect insulin secretion and has no significant effect on the activities of ERK1, ERK2, or p38.
