U-VUE Biomarker Datasheet - FoxP3

Alternative Name:Forkhead box protein P3, Surfin
Isotype:Mouse IgG1
Main cell types:Regulatory T cells
Subcellular Location:Nuclear
Positive control:Tonsil, Spleen, Lymph Node

FoxP3, or Forkhead Box P3 is a transcription factor important in the development and inhibitory function of regulatory T cells (Tregs). FoxP3 functions by inhibiting cytokine production and T cell effector function, thus playing a crucial role in maintanance of immunological tolerance and control of immune responses against tumors and pathogens.
