  • The homeodomain is a 60-amino-acid-long DNA-binding domain (encoded by its corresponding 180-base-pair DNA sequence, the homeobox). (wikipedia.org)
  • The homeodomain domain is generally composed of about 60 amino acids encoded homeobox, which form three alpha helices. (biomedcentral.com)
  • The WOX genes form a plant-specific subclade of the eukaryotic homeobox transcription factor superfamily, which is characterized by the presence of a conserved DNA-binding homeodomain. (gao-lab.org)
  • The proteins encoded by homeobox genes are called HOMEODOMAIN PROTEINS. (lookformedical.com)
  • Most HDs are able to bind DNA as monomers with high affinity, through interactions made by helix III (the so-called recognition helix) and a disordered N-terminal arm located beyond helix I. The high degree of conservation of this type of domain among diverse proteins from different kingdoms indicates that this structure is crucial to maintain the HD functionality and that the role played by this domain is vital. (gao-lab.org)
  • Based on previous phylogenetic analyses in arabidopsis ( Arabidopsis thaliana ), our results showed that some tomato SL-ZH ( S. lycopersicum zinc-finger homeodomain) genes cluster into the same neighbor-joining (NJ) branch as arabidopsis, indicating that these genes may share similar structures and functions in these plants. (ashs.org)
  • Contrary to previous predictions, the dimerization interface involves the carboxyl terminus of the DNA recognition helix of the homeodomain, which in an extended conformation interacts with specific residues at the amino terminus of helix alpha1 and in the loop between helices alpha3 and alpha4 of the POU-specific domain of the symmetry related monomer.
