The FOXP4 gene (Forkhead Box P4) encodes a transcription factor involved in embryonic development, organogenesis, and neuronal differentiation. FOXP4 is a member of the FOX (Forkhead Box) transcription factor family and plays important roles in lung development, cardiac morphogenesis, and central nervous system function.
Key points:
- Located on chromosome 6p12.1
- Forkhead transcription factor
- Expressed in developing brain and multiple organs
- Associated with congenital heart disease and cancer
Foxp4 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
FOXP4 is a forkhead/winged-helix transcription factor that regulates gene expression during development and in adult tissues.

The FOXP4 gene spans approximately 40 kb and contains 18 exons. It encodes a protein of 680 amino acids.
FOXP4 contains:
- Forkhead domain (FH): DNA-binding region (amino acids 170-270)
- Leucine zipper: Protein dimerization
- Transcriptional repression domain: C-terminal
FOXP4 functions as a transcriptional repressor:
- Transcriptional regulation: Binds to forkhead DNA motifs
- Development: Regulates lung, heart, and neural development
- Cell proliferation: Controls cell cycle genes
- Cancer biology: Altered expression in various cancers
