  • Function
    Transcriptional 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 specificity
    Isoform 1 and isoform 6 are expressed in adult and fetal brain, caudate nucleus and lung.
  • Involvement in disease
    Defects 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 similarities
    Contains 1 C2H2-type zinc finger.
    Contains 1 fork-head DNA-binding domain.
  • Developmental stage
    Expressed 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.

Thank you for your email. I have checked with the originator of this antibody who has provided me with the following information regarding your question. It seems that since the design of Ab1307, more members of the FOXP family have been identified, including other isoforms of FOXP2. We agree that there remains a possibility of cross-reaction with FOXP1 and FOXP4. Here is some data with the C-terminus in the third column and molecular weight in the fourth column: FOXP2 isoform 1 reieeeplsedle 79919 MW NP_055306 isoform 2 reieeeplsedle 82551 MW NP_683696 isoform 3 reieeeplsedle 70104 MW NP_683698 FOXP1 rdyedepvnedme 75317 MW NP_116071 FOXP4 rdleeelpgeels 72216 MW NP_612466 We haven't tested specifically for cross-reaction and can only be confident about our own data - which we have added to the datasheet: The WB in the data sheet of Ab1307 on mouse brain lysate indicate a clear ~75kDa band, and a weaker band of slightly higher molecular weight. Ab1307 stains acetone fixed cytospin preparation of Cos cells transfected with full length human FOX P2 cDNA by immunocytochemistry. Unfortunately we have no plans for specific tests of cross-reactivity and don’t have access to purified FOXP1, 2 or 4, nor have we access to knock-out tissue or the relevant peptides. We would be very grateful for any feedback from users on this point. With regard to the refund policy, we can only offer refunds if the product does not perform as described on this datasheet. However, Abcam does provide rewards for feedback from customers who have used our products. If you decide to go ahead and purchase this product, please let us know how you get on and in return we will award you 50 points with the Abcam Loyalty Scheme which can be redeemed on a number of rewards.
