MIP-1β is produced by various cell types, including macrophages, dendritic cells, and lymphocytes. The protein is a non-glycosylated molecule consisting of 69 amino acids and has a molecular mass of approximately 7.6 kDa . It is encoded by the CCL4 gene and is known for its ability to form heterodimers with another chemokine, MIP-1α (CCL3), which can enhance its biological activity .
MIP-1β is primarily involved in the immune response and has several key functions:
Due to its significant role in immune responses, MIP-1β has been studied extensively in various clinical contexts:
Recombinant human MIP-1β is produced using recombinant DNA technology, typically in bacterial expression systems such as Escherichia coli. The recombinant protein is used in research to study its biological functions and potential therapeutic applications. It is available in various forms, including lyophilized powder, and is often used in assays to measure its activity and interactions with other molecules .
In conclusion, Macrophage Inflammatory Protein-1 Beta (MIP-1β/CCL4) is a critical chemokine with diverse roles in immune regulation, inflammation, and antiviral defense. Its recombinant form is a valuable tool in biomedical research, contributing to our understanding of immune responses and the development of potential therapies for various diseases.
