α₁-PDX, Human, Recombinant, E. coli

Recombinant protein derived from the bioengineered human α₁-antitrypsin gene fused to a His•Tag sequence and a FLAG-tag. Contains a minimal furin consensus sequence, RXXR, that effectively blocks the furin-dependent processing of protein precursors (K_i = 600 pM). Extracellular application of α₁-PDX can be used to inhibit the processing of biologically significant proteins including viral envelope glycoproteins, bacterial toxins, receptors, and growth factors. Useful for in vivo and in vitro furin inhibition assays.

Cell permeable: no

Primary Target
Furin-dependent processing of protein precursors

Product does not compete with ATP.

Reversible: no

Target K_i: 600 pM against furin-dependent processing of protein precursors
