Forkhead Box Protein P3 (FOXP3) ELISA Kit for Human

The protein encoded by this gene is a member of the forkhead/winged-helix family of transcriptional regulators. Defects in this gene are the cause of immunodeficiency polyendocrinopathy, enteropathy, X-linked syndrome (IPEX), also known as X-linked autoimmunity-immunodeficiency syndrome. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

FOXP3: Probable transcription factor. Plays a critical role in the control of immune response. Interacts with IKZF3. 3 isoforms of the human protein are produced by alternative splicing.
