Biotinylated synthetic triacylated lipopeptide

Pam3CSK4 is a synthetic triacylated lipopeptide (LP) that mimics the acylated amino terminus of bacterial LPs.

Pam3CSK4 is a potent activator of the proinflammatory transcription factor NF-κB.

Activation is mediated by the interaction between TLR2 and TLR1 which recognize LPs with three fatty acids, a structural characteristic of bacterial LPs.

Bacterial lipoproteins are a family of proinflammatory cell wall components found in both Gram positive and Gram negative bacteria.

The stimulatory activity of bacterial lipoproteins resides in their acylated amino terminus.

Pam3CSK4 is a synthetic tripalmitoylated lipopeptide that mimicks the acylated amino terminus of bacterial lipoproteins.

Pam3CysSerLys4 (Pam3CSK4) is a potent activator of the proinflammatory transcription factor NF-κB [1].

Recognition of Pam3CSK4 is mediated by TLR2 which cooperates with TLR1 through their cytoplasmic domain to induce the signaling cascade leading to the activation of NF-κB [2].
