motifs/domains
  • a transcriptional repression domain including a zinc-finger motif in the N-terminal region
  • a nuclear localization signal domains
  • a polyglutamine tract
  • a forkhead (FH, winged helix) domain evolutionally conserved domain of approximately 110 AA, important for both DNA binding ability and nuclear localization, forming a helix-turn-helix DNA binding motif dubbed the winged-helix
  • one C2H2 type zinc finger

    basic FUNCTION
  • involved in neural mechanisms mediating the development of speech and language
  • transcriptional repressor playing an important role in the specification and differentiation of lung epithelium
  • playing a role in the development of corticostriatal and olivocerebellar circuits involved in motor control
  • involved in acquiring human speech/language ability
  • involved in multiple functions not related to higher cognitive functions, including sensorimotor integration and vocal learning in birds and lung development outside the CNS
  • crucial regulator of lung and esophageal development, underscoring the necessity of this transcription factor in the development of anterior foregut-derived tissues
  • implicated in developmental verbal dyspraxia, a speech and language disorder
  • is important for modulating the plasticity of relevant neural circuits
  • FOXP1 and FOXP2 may be involved in the determination of the cell type identities during late embryogenesis
  • has an important role in speech and language in humans, and its targets may have a critical function in the development and evolution of language circuitry
  • in combination with PBX3 and MEIS2, may play a pivotal role in the development of striosomal neurons of the striatum and the islands of Calleja
  • down-regulates both the SRPX2 and the PLAUR genes and this transcriptional regulation is lost when FOXP2 bears a pathogenic p.R553H mutation that is known to cause DVD (developmental verbal dyspraxia)
  • modulates neuronal network formation, by directly and indirectly regulating mRNAs involved in the development and plasticity of neuronal connections
  • FOXP2 might functionally regulate DISC1 expression
  • FOXP2, DISC1 and the NRXN family in a molecular network that, when altered, confers risk for neurodevelopmental conditions in which various aspects of linguistic and cognitive function are disturbed, possibly via aberrant synaptic function
  • implicated in the development of cortico-striatal circuits, which are involved in sensorimotor integration required for vocal motor learning
  • implicated in pathways regulating neurite outgrowth, axon guidance and synaptic plasticity, which is in agreement with a role of FOXP2 in the development of neural circuits for language development
