**Background of ITGAM Recombinant Protein**
ITGAM (Integrin Alpha M), also known as CD11b, is a critical subunit of the heterodimeric integrin receptor Mac-1 (αMβ2. CD11b/CD18). It is predominantly expressed on myeloid cells, including neutrophils, monocytes, and macrophages, where it mediates cell adhesion, migration, and immune responses. ITGAM plays a pivotal role in pathogen recognition, phagocytosis, and immune cell activation by interacting with ligands such as complement component iC3b, fibrinogen, and intercellular adhesion molecules (ICAMs). Dysregulation of ITGAM is linked to inflammatory diseases (e.g., lupus, atherosclerosis) and cancer progression.
Recombinant ITGAM protein is engineered *in vitro* using expression systems like mammalian cells (e.g., HEK293) or bacteria (e.g., *E. coli*), ensuring high purity and bioactivity. It typically includes functional domains such as the extracellular ligand-binding region (I-domain), crucial for studying interactions with partners like iC3b or ICAM-1. Researchers employ ITGAM recombinant proteins to investigate leukocyte trafficking, inflammation mechanisms, and immune signaling pathways. It also serves as a tool for drug screening, antibody development, and diagnostic assays (e.g., ELISA, flow cytometry).
In therapeutic contexts, recombinant ITGAM aids in designing inhibitors to block excessive inflammation or autoimmune responses. Mutant variants of ITGAM (e.g., linked to lupus risk) are similarly produced to dissect disease-associated functional alterations. Overall, ITGAM recombinant proteins are indispensable for advancing immunology research and translational applications.
