**Background of IRAK3 Recombinant Protein**
Interleukin-1 receptor-associated kinase 3 (IRAK3), also known as IRAK-M, is a member of the IRAK family of serine/threonine kinases, which play critical roles in innate immune signaling. Unlike other IRAK family members (e.g., IRAK1 and IRAK4), IRAK3 lacks kinase activity and functions primarily as a negative regulator of Toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) signaling pathways. It is expressed predominantly in immune cells, including macrophages and monocytes, where it modulates inflammatory responses to prevent excessive activation.
IRAK3 acts by inhibiting the dissociation of IRAK1 and IRAK4 from the receptor complex, thereby blocking downstream signaling events such as NF-κB and MAPK activation. This regulatory mechanism helps maintain immune homeostasis and prevents tissue damage from uncontrolled inflammation. Dysregulation of IRAK3 has been linked to chronic inflammatory diseases, autoimmune disorders, and cancer. For instance, IRAK3 overexpression is associated with immunosuppression in certain cancers, while its deficiency can exacerbate inflammatory conditions like sepsis or colitis.
Recombinant IRAK3 protein is produced using expression systems (e.g., *E. coli* or mammalian cells) to study its structure, interactions, and regulatory mechanisms. It serves as a tool for investigating TLR/IL-1R signaling modulation, screening potential anti-inflammatory or anticancer drugs, and understanding immune tolerance. Research on IRAK3 recombinant protein holds promise for developing therapies targeting inflammation-related diseases and immune checkpoint regulation.
