homeobox
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): homeodomainhomeobox (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.AcronymsSeeHOXhomeobox
