Serpin A4, Human (HEK293, His)

Serpin A4 Protein inhibits tissue kallikrein's amidolytic and kininogenase activities by forming a heat- and SDS-stable equimolar complex with the enzyme. Tissue kallikrein concurrently cleaves the reactive site of Serpin A4, producing a small C-terminal fragment. The protein, existing as a monomer and occasionally forming homodimers, demonstrates its regulatory role in modulating tissue kallikrein-mediated enzymatic activities. Serpin A4 Protein, Human (HEK293, His) is the recombinant human-derived Serpin A4 protein, expressed by HEK293 , with C-6*His labeled tag.
