Transcription factor gene of the forkhead box family
Forkhead box protein P2 (FOXP2 ) is a protein that, in humans, is encoded by the FOXP2 gene . FOXP2 is a member of the forkhead box family of transcription factors , proteins that regulate gene expression by binding to DNA . It is expressed in the brain, heart, lungs and digestive system.[ 5] [ 6]
FOXP2 is found in many vertebrates , where it plays an important role in mimicry in birds (such as birdsong ) and echolocation in bats. FOXP2 is also required for the proper development of speech and language in humans.[ 7] In humans, mutations in FOXP2 cause the severe speech and language disorder developmental verbal dyspraxia .[ 7] [ 8] Studies of the gene in mice and songbirds indicate that it is necessary for vocal imitation and the related motor learning.[ 9] [ 10] [ 11] Outside the brain, FOXP2 has also been implicated in development of other tissues such as the lung and digestive system.[ 12]
Initially identified in 1998 as the genetic cause of a speech disorder in a British family designated the KE family , FOXP2 was the first gene discovered to be associated with speech and language[ 13] and was subsequently dubbed "the language gene".[ 14] However, other genes are necessary for human language development, and a 2018 analysis confirmed that there was no evidence of recent positive evolutionary selection of FOXP2 in humans.[ 15] [ 16]
