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 ...
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 ...
Homeodomain-leucine zipper proteins interact with a plant homologue of the transcriptional coactivator multiprotein bridging factor 1
(Biochemical Society of the Republic of Korea, 2004-12)
StMStMBF1 (Solanum tuberosum multiprotein bridging factor 1) is a plant member of the MBF1 family of transcriptional co-activators. In an attempt to understand the role of StMBF1, we analyzed its interaction with plant ...
The role and effects of glucocorticoid-induced leucine zipper in the context of inflammation resolution
(American Association of Immunologists -, 2016)
Hahb-10, a sunflower homeobox-leucine zipper gene, is regulated by light quality and quantity, and promotes early flowering when expressed in Arabidopsis
(Oxford University Press, 2005-12)
Homeodomain-leucine zipper proteins constitute a family of transcription factors found only in plants. Expression patterns of the sunflower homeobox-leucine zipper gene Hahb-10 (Helianthus annuus homeobox-10), that belongs ...
Functional characterization of the homeodomain leucine zipper i transcription factor AtHB13 reveals a crucial role in Arabidopsis development
(Oxford University Press, 2015-09)
AtHB13 is a homeodomain leucine zipper I transcription factor whose function in development is largely unknown. AtHB13 and AtHB23 mutant and silenced lines were characterized by expression studies, reciprocal crosses, ...
Arabidopsis thaliana HomeoBox 1 (AtHB1), a Homedomain-Leucine Zipper I (HD-Zip I) transcription factor, is regulated by PHYTOCHROME-INTERACTING FACTOR 1 to promote hypocotyl elongation
(Wiley Blackwell Publishing, Inc, 2015-08)
Arabidopsis thaliana HomeoBox 1 (AtHB1) is a homeodomain-leucine zipper transcription factor described as a transcriptional activator with unknown function. Its role in A. thaliana development was investigated. AtHB1 ...
Plant homeodomain-leucine zipper I transcription factors exhibit different functional AHA motifs that selectively interact with TBP or/and TFIIB
(Springer, 2014-06)
Key message: Different members of the HD-Zip I family of transcription factors exhibit differential AHA-like activation motifs, able to interact with proteins of the basal transcriptional machinery. Homeodomain-leucine ...
