General Description
An exocyclic cysteine-knot peptide that specifically antagonizes Fas/FasL-mediated cellular apoptotic signals (58% reduction of FasL-induced apoptosis in Jurkat cells at 1 mg/ml). Binds to FasL (Cat. Nos. PF033 and PF092) and Fas (CD95/APO-1) with comparable affinity (K
d = 11.2 & 13.2 μM, respectively), resulting in disabled receptor ensembles and altered signaling. Shown to prevent Con A (Cat. No. 234567)-induced liver injury in a murine hepatitis model
in vivo. Does not bind to TNF-α or TNFR.
