Positively charged residues at the N-terminal arm of the homeodomain are required for efficient DNA binding by homeodomain-leucine zipper proteins
(Academic Press Ltd - Elsevier Science Ltd, 2001-04)
Plant homeodomain-leucine zipper proteins, unlike most animal homeodomains, bind DNA efficiently only as dimers. In the present work, we report that the deletion of the homeodomain N-terminal arm (first nine residues) of ...
Interaction of the BELL-like protein ATH1 with DNA: Role of homeodomain residue 54 in specifying the different binding properties of BELL and KNOX proteins
(De Gruyter, 2006-01)
We have studied the interaction of the BELL-like Arabidopsis homeodomain protein ATH1 with DNA. Analysis of oligonucleotides selected by the ATH1 homeodomain from a random mixture suggests that ATH1 preferentially binds ...
Localization of rDNA sites in holocentric chromosomes of three species of triatomines (Heteroptera, Triatominae).
(2005-12-30)
Chromatin organization in the holocentric chromosomes of three triatomines species was cytologically studied by fluorescent in situ hybridization with a 45S rDNA probe of Drosophila melanogaster to localize ribosomal genes. ...

Mandible metastasis as the first sign from primary adenocarcinoma of the lung
(2007-05-01)
Adenocarcinoma of the lung that metastasizes to the mandible is very uncommon; only a few cases have been described in the English-language literature. This article presents a metastasis from adenocarcinoma of the lung ...

Structure of homeodomain-leucine zipper/DNA complexes studied using hydroxyl radical cleavage of DNA and methylation interference
(American Chemical Society, 2005-12)
Homeodomain-leucine zipper (HD-Zip) proteins, unlike most homeodomain proteins, bind a pseudopalindromic DNA sequence as dimers. We have investigated the structure of the DNA complexes formed by two HD-Zip proteins with ...
Conserved homeodomain cysteines confer redox sensitivity and influence the DNA binding properties of plant class III HD-Zip proteins
(Elsevier Science Inc, 2007-11)
The role of four cysteines present within the homeodomain of the homeodomain-leucine zipper (HD-Zip) class III protein Athb-9 has been studied. DNA binding by the Athb-9 HD-Zip domain was only observed after incubation in ...
