Genes affected

MIF-AS1 (HGNC:27669): (MIF antisense RNA 1)

MIF-AS1 links:

MIF (HGNC:7097): (macrophage migration inhibitory factor) 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.
