NCIt synonyms : Homeobox Family Gene; Homeodomain Gene; Hox Gene;
NCIt definition : A family of genes that contain a highly conserved sequence of approximately 180 nucleotides,
which encode an approximately 60 amino acid helix-turn-helix DNA binding domain made
up of 2 antiparallel alpha helices and one nearly perpendicular alpha helix connected
by short chains of unstructured amino acid sequences. This gene family is involved
in transcriptional regulation during embryonic development.;
