The DLX5 gene encodes Distal-Less Homeobox 5, a member of the DLX family of homeodomain transcription factors essential for craniofacial development, limb formation, and central nervous system development. DLX5 plays crucial roles in the development of GABAergic inhibitory neurons in the forebrain, particularly in the olfactory bulb, cerebral cortex, and basal ganglia. Located on chromosome 7q22.1, this gene is part of a conserved gene cluster with DLX6, and both are co-expressed during development.
The DLX5 gene spans approximately 4.5 kb and contains 3 exons encoding a protein of 325 amino acids. Key regulatory features include:
DLX5 protein is characterized by:
The protein functions as a homodimer or heterodimer with other DLX proteins, binding to TAAT/ATTA motifs in target gene promoters.
