A highly conserved sequence of 180 nucleotides common to many regulatory genes and coding for the DNA-binding part of the corresponding regulatory proteins. ~ See Also: Homeotic gene, Transcription factor.
A 180-base-pair sequence that is present in many developmental genes of animals and plants. It encodes a DNA-binding helix–turn–helix motif, indicating that homeobox-containing gene products function as transcription factors.
A DNA-binding motif found in many proteins involved in developmental regulation of gene expression.
