homeobox

ho·me·o·box

H0251450 (hō′mē-ə-bŏks′)n. A short DNA sequence contained within all homeobox genes that codes for a specific amino acid sequence that binds to DNA and regulates transcription.

[homeo(tic gene) + box (from the fact that the DNA sequence is short and when written can be enclosed by a box on paper).]

homeobox

[′hō·mē·ə‚bäks] (cell and molecular biology) A highly conserved sequence of deoxyribonucleic acid (DNA) that occurs in the coding region of development-controlling regulatory genes and codes for a protein domain that is similar in structure to certain DNA-binding proteins and is thought to be involved in the control of gene expression during morphogenesis and development.

homeobox

ho·me·o·box

(hō'mē-ō-boks), A highly conserved DNA sequence of about 180 base pairs near the 3' end of specific homeotic genes; it encodes a DNA-binding domain that allows the homeobox proteins to bind to and regulate gene expression in development. Synonym(s): homeodomain

homeobox

(hō′mē-ə-bŏks′)n. A sequence of DNA encoding a protein structure that binds to specific parts of DNA and affects transcription of DNA into RNA.

homeobox

a conserved DNA motif of about 180bp encoding a protein domain (approximately 60 amino acids) that binds to DNA. The homeobox is a characteristic of HOMEOTIC GENES and is found in most EUKARYOTES.
