Recombinant Human CXCR4 Protein，His

CXCR4, a chemokine receptor, plays a crucial role in various physiological and pathological processes, including hematopoiesis, immune response, and cancer metastasis. The receptor is primarily known for its involvement in the migration of immune cells, particularly T cells and stem cells, to sites of infection or inflammation. Its interaction with the ligand CXCL12 (also known as SDF-1) is vital for these processes. Research has shown that CXCR4 is overexpressed in several types of cancers, contributing to tumor progression, metastasis, and resistance to therapy. Given its significant role in these critical biological functions, CXCR4 has emerged as an attractive therapeutic target. The development of CXCR4 recombinant proteins is essential for understanding its structure-function relationships, molecular mechanisms of action, and interactions with ligands and drugs. These recombinant proteins pave the way for the exploration of CXCR4's role in disease and the development of novel therapeutic strategies, including CXCR4 antagonists that could inhibit cancer metastasis and improve therapeutic outcomes in patients. Additionally, the study of CXCR4 recombinant proteins can enhance our understanding of other conditions, such as HIV infection, where CXCR4 acts as a co-receptor, thereby facilitating the search for new antiviral therapies. Overall, the research surrounding CXCR4 recombinant proteins stands at the intersection of immunology, oncology, and pharmacology, aiming to unlock new insights into therapy and enhance clinical applications.
