Descrizione

Descrizione generale

A cell-permeable synthetic peptide containing mouse TIRAP_138-151 fused to the Drosophila Antennapedia sequence. Specifically inhibits LPS-, but not CpG-induced NF-κB activation, PKR phosphorylation, and JNK phosphorylation in RAW.κB cells at ~40 µM. Also reported to block IκBα degradation.

A synthetic, cell-permeable peptide that corresponds to mouse toll-interleukin 1 receptor (TIR) domain-containing adapter protein 138-151 (TIRAP; also called Mal (MyD88-adapter-like), fused to the Drosophila antennapedia sequence. Shown to specifically inhibit LPS-induced, but not CpG-induced, NF-κB activation, PKR phosphorylation, and JNK phosphorylation in RAW.κB cells at ~40 µM. Also reported to block IκBα degradation.
