Pepinh-MYD - MyD88 Inhibitor

MyD88 Inhibitory Peptide

Pepinh-MYD is a 26 aa peptide that blocks MyD88 signaling by inhibiting its homodimerization through binding.

Pepinh-MYD contains a sequence from the MyD88 TIR homodimerization domain (RDVLPGT) [1] preceeded by a protein transduction sequence (RQIKIWFQNRRMKWKK) derived from antennapedia which enables the peptide to translocate through the cell membrane [2].

Pepinh-MYD is provided with Pepinh-Control, a control peptide [3].
