NCBI and Uniprot Product Information
NCBI Description
This gene encodes a lymphokine involved in cell-mediated immunity, immunoregulation, and inflammation. It plays a role in the regulation of macrophage function in host defense through the suppression of anti-inflammatory effects of glucocorticoids. This lymphokine and the JAB1 protein form a complex in the cytosol near the peripheral plasma membrane, which may indicate an additional role in integrin signaling pathways.

Uniprot Description
Function: Pro-inflammatory cytokine. Involved in the innate immune response to bacterial pathogens. The expression of MIF at sites of inflammation suggests a role as mediator in regulating the function of macrophages in host defense. Counteracts the anti-inflammatory activity of glucocorticoids. Has phenylpyruvate tautomerase and dopachrome tautomerase activity (in vitro), but the physiological substrate is not known. It is not clear whether the tautomerase activity has any physiological relevance, and whether it is important for cytokine activity. Ref.23 Ref.24
Catalytic activity: Keto-phenylpyruvate = enol-phenylpyruvate. Ref.32 Ref.34L-dopachrome = 5,6-dihydroxyindole-2-carboxylate. Ref.32 Ref.34
Subunit structure: Homotrimer. Interacts with CXCR2 extracellular domain
By similarity. Interacts with the CD74 extracellular domain, COPS5 and BNIPL. Ref.18 Ref.21 Ref.22 Ref.25 Ref.33 Ref.34
Subcellular location: Secreted. Cytoplasm. Note: Does not have a cleavable signal sequence and is secreted via a specialized, non-classical pathway. Secreted by macrophages upon stimulation by bacterial lipopolysaccharide (LPS), or by M.tuberculosis antigens. Ref.1 Ref.2 Ref.18 Ref.23 Ref.25
Induction: Up-regulated in concanavalin-A-treated lymphocytes. Up-regulated in macrophages upon exposure to M.tuberculosis antigens. Ref.1 Ref.23
Involvement in disease: Rheumatoid arthritis systemic juvenile (RASJ) [MIM:604302]: An inflammatory articular disorder with systemic-onset beginning before the age of 16. It represents a subgroup of juvenile arthritis associated with severe extraarticular features and occasionally fatal complications. During active phases of the disorder, patients display a typical daily spiking fever, an evanescent macular rash, lymphadenopathy, hepatosplenomegaly, serositis, myalgia and arthritis.Note: Disease susceptibility is associated with variations affecting the gene represented in this entry.
Miscellaneous: Serum levels of MIF are elevated in patients with severe sepsis or septic shock. High levels of MIF are correlated with low survival. Drugs that inhibit tautomerase activity protect against death due to sepsis.
Sequence similarities: Belongs to the MIF family.

Product Notes
The MIF mif (Catalog #AAA650444) is a Recombinant Protein and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Migration Inhibitory Factor can be used in a range of immunoassay formats including, but not limited to, ELISA (EL/EIA). Researchers should empirically determine the suitability of the MIF mif for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Migration Inhibitory Factor, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
