This domain, approximately 60-70 residues in length, is mainly found in Forkhead box proteins in various Mammalia species [1]. It is a coiled-coil domain, which modulates the dimeric associations of FOXP transcription factors. Several key disease mutations, for instance those found in the IPEX syndrome are located in this domain [2]	Domain
