背景信息

**Background of IRAK2 Recombinant Protein**

Interleukin-1 receptor-associated kinase 2 (IRAK2) is a critical signaling molecule in the innate immune system, primarily involved in Toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) pathways. As a member of the IRAK family, IRAK2 acts downstream of myeloid differentiation primary response 88 (MyD88), forming signaling complexes that activate NF-κB and mitogen-activated protein kinase (MAPK) pathways. These pathways drive the production of pro-inflammatory cytokines and chemokines, essential for initiating immune responses against pathogens. Unlike IRAK1 and IRAK4. IRAK2 lacks canonical kinase activity in certain contexts but serves as a scaffolding protein to amplify and sustain inflammatory signals, contributing to both acute and chronic inflammation.

IRAK2 exists in two splice variants (IRAK2a and IRAK2b) with distinct regulatory roles. Dysregulation of IRAK2 is linked to autoimmune diseases (e.g., rheumatoid arthritis), chronic inflammation, and cancer, making it a potential therapeutic target. Recombinant IRAK2 proteins are engineered *in vitro* using expression systems (e.g., *E. coli* or mammalian cells) to study its structure, post-translational modifications, and interactions. These proteins enable *in vitro* kinase assays, inhibitor screening, and mechanistic studies of IRAK2’s role in inflammasome activation (e.g., NLRP3) or TLR signaling.

Research on IRAK2 recombinant proteins also explores its pseudokinase domain and death domain, which mediate protein-protein interactions. Understanding IRAK2’s regulatory mechanisms could lead to novel anti-inflammatory or anti-cancer therapies, particularly for diseases driven by hyperactive NF-κB signaling.
