  • FunctionTranscriptional repressor that may play a role in the specification and differentiation of lung epithelium. May also play a role in developing neural, gastrointestinal and cardiovascular tissues. Can act with CTBP1 to synergistically repress transcription but CTPBP1 is not essential. Involved in neural mechanisms mediating the development of speech and language.
  • Tissue specificityIsoform 1 and isoform 6 are expressed in adult and fetal brain, caudate nucleus and lung.
  • Involvement in diseaseDefects in FOXP2 are the cause of speech-language disorder 1 (SPCH1) [MIM:602081]; also known as autosomal dominant speech and language disorder with orofacial dyspraxia. Affected individuals have a severe impairment in the selection and sequencing of fine orofacial movements, which are necessary for articulation. They also show deficits in several facets of language processing (such as the ability to break up words into their constituent phonemes) and grammatical skills.
    Note=A chromosomal aberration involving FOXP2 is a cause of severe speech and language impairment. Translocation t(5;7)(q22;q31.2).
  • Sequence similaritiesContains 1 C2H2-type zinc finger.
    Contains 1 fork-head DNA-binding domain.
  • Developmental stageExpressed in the brain at 15 and 22 weeks of gestation, with a pattern of strong cortical, basal ganglia, thalamic and cerebellar expression. Highly expressed in the head and tail of nucleus caudatus and putamen. Restricted expression within the globus pallidus, with high levels in the pars interna, which provides the principal source of output from the basal ganglia to the nucleus centrum medianum thalami (CM) and the major motor relay nuclei of the thalamus. In the thalamus, present in the CM and nucleus medialis dorsalis thalami. Lower levels are observed in the nuclei anterior thalami, dorsal and ventral, and the nucleus parafascicularis thalami. Expressed in the ventrobasal complex comprising the nucleus ventralis posterior lateralis/medialis. The ventral tier of the thalamus exhibits strong expression, including nuclei ventralis anterior, lateralis and posterior lateralis pars oralis. Also expressed in the nucleus subthalamicus bilaterally and in the nucleus ruber.

  • ab1307 staining FOXP2 in e12.5 mouse embryonic spinal cord tissue sections by Immunohistochemistry (frozen sections). Tissue was fixed with paraformaldehyde and then blocked with 10% serum for 30 minutes at 20°C followed by incubation with the primary antibody, at a 1/1000 dilution, for 16 hours at 4°C. The secondary antibody used was a donkey anti-sheep (and goat) IgG conjugated to Alexa Fluor® 594 (red) used at a 1/2000 dilution.
