HpARI (CCP1/2) (rec.) (His) MultiPack

Product Description: HpARI is a protein secreted by the mouse parasite Heligmosomoides polygyrus. The mature protein HpARI, containing three predicted Complement Control Protein (CCP)-like modules (also known as Short Consensus Repeats (SCRs) or sushi-domains), suppresses type 2 (allergic) immune responses through interference in the interleukin-33 (IL-33) pathway. During cell damage, HpARI gains access to the nucleus of necrotic cells, where it binds directly to IL-33 and nuclear DNA, preventing secretion and binding of IL-33 to its receptor. A non-natural truncation consisting of the first 2 domains of HpARI (CCP1/2) retains IL-33 and DNA binding capacity. HpARI (CCP1/2) is able to stabilize IL-33, increasing its half-life and amplifying its effects. HpARI (CCP1/2) increases IL-33 activity by protecting it from oxidation and proteolytic degradation. HpARI (CCP1/2) (rec.) (His) is a new type of reagent to study IL-33-mediated pathology in vivo.

Alternate Names/Synonyms: Heligmosomoides Polygyrus Alarmin Release Inhibitor Truncated (CCP1/2); HpARI Truncation Lacking CCP3
