Homeobox

A homeobox is a DNA sequence found within genes that are involved in the regulation of development (morphogenesis) of animals, fungi and plants. Genes that have a homeobox are called homeobox genes and form the homeobox gene family.

Noun
1. one of various similar homeotic genes that are involved in bodily segmentation during embryonic development
(synonym) homeobox gene
(hypernym) homeotic gene

A short stretch of nucleotides (DNA or RNA) with an almost identical base sequence in all genes that contain that stretch. Homeoboxes occur in many organisms from fruit flies to human beings and appear to determine when particular groups of genes are expressed during development.

Conserved protein sequence which forms a DNA-binding domain in a class of transcription factors.
