A
consensus sequence of about 180 base pairs discovered in homeotic
genes in Drosophila. Also found in other developmentally important
genes from yeast to human beings. A family of quite similar l80base-pair
DNA sequences that encode a polypeptide sequence called a homeo-domain,
a sequence-specific DNA binding sequence. While the homeobox was first
discovered in all homeotic genes, it is now known to encode a much
more widespread DNA-binding motif. |
