| additional information | Homo sapiens | the enzyme plays an important physiological role in the defense mechanism against a variety of infectious pathogens, in the regulation of T-cell function by macrophages and a subset of dendritic cells, and in the synthesis of UV filters in human lenses. Serious problems arise from the unregulated over-expression of the enzyme, which often results in a deleterious systemic Trp depletion and/or the accumulation of neurotoxin, quinolinic acidn the brain. Enzyme expression in malignant tumors helps them to avoid the immune surveillance through a local Trp depletion. The kynurenilation of the lens protein with UV filters thus appears to be the major cause of age-related cataract | ? | - |
