Description

Amino Acid Sequence

NAc-Ile-Glu-Thr-Asp-pNA

Application

Chromogenic substrate for caspase 8 and granzyme B.

Biochem/physiol Actions

IETD is the sequence of amino acid residues 172-175 of procaspase 3, which is cleaved during apoptosis to produce the p12 subunit and a p20 peptide that is further cleaved to form the p17 subunit of mature caspase 3.
