Protocol
Specificity / Sensitivity
FoxP3 (D6O8R) Rabbit mAb recognizes endogenous levels of total FoxP3 protein. This antibody recognizes mouse FoxP3 protein and is also reactive with human FoxP3; however, this antibody is not suggested for immunohistochemical analysis of human tissues. Instead, FoxP3 (D2W8E™) Rabbit mAb (IHC Specific) #98377 is recommended for IHC analysis of human tissue samples. Monkey cross-reactivity is determined by immunohistochemistry.
Species Reactivity:
Mouse, Monkey
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro44 of mouse FoxP3 protein.
Background
Forkhead box (Fox) proteins are a family of evolutionarily conserved transcription factors containing a sequence known as Forkhead box or winged helix DNA binding domain (1). The human genome contains 43 Fox proteins that are divided into subfamilies. The FoxP subfamily has four members, FoxP1 - FoxP4, which are broadly expressed and play important roles in organ development, immune response, and cancer pathogenesis (2-4). The FoxP subfamily has several characteristics that are atypical among Fox proteins: their Forkhead domain is located at the carboxy-terminal region and they contain motifs that promote homo- and heterodimerization. FoxP proteins usually function as transcriptional repressors (4,5).
FoxP3 is crucial for the development of T cells with regulatory properties (Treg) (6). Mutations in FoxP3 are associated with immune dysregulation, polyendocrinopathy, enteropathy, and X-linked syndrome (IPEX) (7), while overexpression in mice causes severe immunodeficiency (8). Research studies have shown that FoxP3 functions as a tumor suppressor in several types of cancer (9-11).
