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 ...
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 ...
Plant transcription factors from the homeodomain-leucine zipper family I. Role in development and stress responses
(John Wiley & Sons Inc, 2017-05)
In front of stressful conditions plants display adaptation mechanisms leading to changes in their morphology, physiology, development and molecular composition. Transcription factors (TFs) play crucial roles in these complex ...
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 ...
Combinatorial interactions of two amino acids with a single base pair define target site specificity in plant dimeric homeodomain proteins
(Oxford University Press, 2001-12)
Four groups of plant homeodomain proteins contain a dimerization motif closely linked to the homeodomain. We here show that two sunflower homeodomain proteins, Hahb-4 and HAHR1, which belong to the Hd-Zip I and GL2/Hd-Zip ...
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 ...
