FoxP3: ELISA Kits

Human FOXP3 is a 47 kDa member of the P subclass of the forkhead box family of transcription factors. It contains a Leu-rich repeat, a C2H2 zinc finger region, and a C-terminal FKH (forkhead) DNA-binding domain. In human, FOXP3 is found in CD4+, CD8+ and CD4+CD25+ T cells and directly associates with NFAT and NFkB, suppressing their activity in CD4+ T cells.
