Winged-helix transcription factors
Consisting of about 110 amino acids, the domain in winged-helix transcription factors has four helices and a two-strand beta-sheet.
Additional recommended knowledge
These proteins are classified into 17 families called FoxA-FoxQ.
Mutations in FoxP proteins are implicated in human autoimmune diseases.
