Forkhead box P3 (FoxP3), aka Scurfin and JM2, is a protein involving in immune system responses and functioning as a transcriptional regulator crucial in the development and inhibitory of regulatory T-Cells (Treg). FoxP3 is a master regulator of the Treg lineage, who requires Ahr and STAT-5 and other additional transcription factors to retains its complete function and differentiation. Scurfin remains steady and constitutively expressed in two conditions: a high level in CD25 + CD4 positive regulatory T cells and a low level in CD4 positive/CD25 negative cells. JM2 is absent in CD4 negative/CD8 positive T cells. FoxP3 defects are related to various cancers and autoimmune diseases, and X-linked syndrome (IPEX), while overexpression may also cause severe immunodeficiency.
