[[http://www.uniprot.org/uniprot/IFNG_HUMAN IFNG_HUMAN]] In Caucasians, genetic variation in IFNG is associated with the risk of aplastic anemia (AA) [MIM:[http://omim.org/entry/609135 609135]]. AA is a rare disease in which the reduction of the circulating blood cells results from damage to the stem cell pool in bone marrow. In most patients, the stem cell lesion is caused by an autoimmune attack. T-lymphocytes, activated by an endogenous or exogenous, and most often unknown antigenic stimulus, secrete cytokines, including IFN-gamma, which would in turn be able to suppress hematopoiesis. | [[http://www.uniprot.org/uniprot/IFNG_HUMAN IFNG_HUMAN]] In Caucasians, genetic variation in IFNG is associated with the risk of aplastic anemia (AA) [MIM:[http://omim.org/entry/609135 609135]].

IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions. It is a potent activator of macrophages, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons. | [[http://www.uniprot.org/uniprot/IFNG_HUMAN IFNG_HUMAN]] Produced by lymphocytes activated by specific antigens or mitogens.

+ | The x-ray crystal structure of recombinant human interferon-gamma has been determined with the use of multiple-isomorphous-replacement techniques. Interferon-gamma, which is dimeric in solution, crystallizes with two dimers related by a noncrystallographic twofold axis in the asymmetric unit. The protein is primarily alpha helical, with six helices in each subunit that comprise approximately 62 percent of the structure; there is no beta sheet. The dimeric structure of human interferon-gamma is stabilized by the intertwining of helices across the subunit interface with multiple intersubunit interactions. | ||
