The Arabidopsis basic/helix-loop-helix transcription factor family.
The basic/helix-loop-helix (bHLH) proteins are a superfamily of transcription factors that bind as dimers to specific DNA target sites and that have been well characterized in nonplant eukaryotes as important regulatory components in diverse biological processes. Based on evidence that the bHLH protein PIF3 is a direct phytochrome reaction partner in the photoreceptor's signaling network, we ha...
متن کاملMembers of the HRT family of basic helix-loop-helix proteins act as transcriptional repressors downstream of Notch signaling.
The Hairy-related transcription-factor (HRT) genes encode three related basic helix-loop-helix transcription factors that show sequence similarity to the Hairy and Enhancer of split family of transcriptional repressors. HRT proteins are expressed in specific regions of the developing heart, vasculature, pharyngeal arches and somites, and the periodicity of their expression in somitic precursors...
متن کاملThe basic helix-loop-helix transcription factor Nato3 controls neurogenic activity in mesencephalic floor plate cells.
Floor plate (FP) cells, the ventral midline cells of the developing neural tube, have long been thought to be non-neurogenic organizer cells that control neuronal patterning and axonal guidance. Recent studies have revealed that mesencephalic FP (mesFP) cells have neurogenic activity and generate dopaminergic neurons. However, the mechanisms underlying the control of neurogenic potential in FP ...
متن کاملTranscriptional repression by the basic helix-loop-helix protein Dec2: multiple mechanisms through E-box elements.
Dec2, a member of the basic helix-loop-helix (bHLH) superfamily, has been shown to function as a transcriptional repressor and is implicated in cell proliferation and differentiation. In addition, Dec2 transcripts exhibit a striking circadian oscillation in the suprachiasmatic nucleus. To identify the molecular mechanisms by which Dec2 regulates gene expression, we carried out structure-functio...
متن کاملThe basic helix-loop-helix transcription factor Mist1 functions as a transcriptional repressor of myoD.
A good model system to examine aspects of positive and negative transcriptional regulation is the muscle-specific regulatory factor, MyoD, which is a basic helix-loop-helix (bHLH) transcription factor. Although MyoD has the ability to induce skeletal muscle terminal differentiation in a variety of non-muscle cell types, MyoD activity itself is highly regulated through protein-protein interactio...
