Cryptochrome 1 Inhibits Shoot Branching by Repressing the Self-Activated Transciption Loop of PIF4 in Arabidopsis

open access: yesPlant Communications, 2020
Cryptochrome 1 (CRY1) is an important light receptor essential for de-etiolation of Arabidopsis seedlings. However, its function in regulating plant architecture remains unclear.

The solution structure of the prototype foamy virus RNase H domain indicates an important role of the basic loop in substrate binding

open access: yesRetrovirology, 2012
Background The ribonuclease H (RNase H) domains of retroviral reverse transcriptases play an essential role in the replication cycle of retroviruses. During reverse transcription of the viral genomic RNA, an RNA/DNA hybrid is created whose RNA strand ...

Phylogenetic analysis of the human basic helix-loop-helix proteins [PDF]

open access: yesGenome Biology, 2002
The basic helix-loop-helix (bHLH) proteins are a large and complex multigene family of transcription factors with important roles in animal development, including that of fruitflies, nematodes and vertebrates. The identification of orthologous relationships among the bHLH genes from these widely divergent taxa allows reconstruction of the putative ...

Basic helix‐loop‐helix transcription factors and enteroendocrine cell differentiation [PDF]

open access: yesDiabetes, Obesity and Metabolism, 2011
For over 30 years it has been known that enteroendocrine cells derive from common precursor cells in the intestinal crypts. Until recently little was understood about the events that result in commitment to endocrine differentiation or the eventual segregation of over 10 different hormone‐expressing cell types in the gastrointestinal tract ...

Identification of a novel family of oligodendrocyte lineage-specific basic helix-loop-helix transcription factors.

open access: yesNeuron, 2000
Basic helix-loop-helix (bHLH) transcription factors have been identified for neurons and their precursors but not for glial cells. We have identified two bHLH factors, Oligo1 and Oligo2, that are specifically expressed in zones of neuroepithelium from ...

An exploration of alternative visualisations of the basic helix-loop-helix protein interaction network

open access: yesBMC Bioinformatics, 2007
Background Alternative representations of biochemical networks emphasise different aspects of the data and contribute to the understanding of complex biological systems.

Genome-Wide Identification of Apple Atypical bHLH Subfamily PRE Members and Functional Characterization of MdPRE4.3 in Response to Abiotic Stress

open access: yesFrontiers in Genetics, 2022
Paclobutrazol Resistance (PRE) genes encode atypical basic helix–loop–helix (bHLH) transcription factor family. Typical bHLH proteins contain a bifunctional structure with a basic region involved in DNA binding and an adjacent helix–loop–helix domain ...

Dissecting the Role of a Basic Helix-Loop-Helix Transcription Factor, SlbHLH22, Under Salt and Drought Stresses in Transgenic Solanum lycopersicum L.

open access: yesFrontiers in Plant Science, 2019
Environmental stresses, such as temperature, heavy metals, drought, cold, and microbial infections adversely damage various aspects of plant growth and development.

The Transcriptional Control of Iron Homeostasis in Plants: A Tale of bHLH Transcription Factors?

open access: yesFrontiers in Plant Science, 2019
Iron is one of the most important micronutrients in plants as it is involved in many cellular functions (e.g., photosynthesis and respiration). Any defect in iron availability will affect plant growth and development as well as crop yield and plant ...

The basic helix-loop-helix (bHLH) proteins in breast cancer progression [PDF]

open access: yesMedical Oncology, 2013
The basic helix-loop-helix (bHLH) proteins are the major transcription factors acting as transcriptional enhancers or inhibitors of various genes through binding to the canonical E-box sequence. The bHLH proteins are highly conserved in both vertebrates and invertebrates.
