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 کاملExocrine specific expression of Connexin32 is dependent on the basic helix-loop-helix transcription factor Mist1.
Gap junctions are intercellular channels that provide direct passage of small molecules between adjacent cells. In pancreatic acini, the connexin26 (Cx26) and connexin32 (Cx32) proteins form functional channels that coordinate the secretion of digestive enzymes. Although the function of Cx26/Cx32 gap junctions are well characterized, the regulatory circuits that control the spatial and temporal...
متن کاملThe grape berry-specific basic helix–loop–helix transcription factor VvCEB1 affects cell size
The development of fleshy fruits involves complex physiological and biochemical changes. After fertilization, fruit growth usually begins with cell division, continues with both cell division and expansion, allowing fruit set to occur, and ends with cell expansion only. In spite of the economical importance of grapevine, the molecular mechanisms controlling berry growth are not fully understood...
متن کاملIdentification of a Novel Family of Oligodendrocyte Lineage-Specific Basic Helix–Loop–Helix Transcription Factors
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 which oligodendrocyte precursors emerge, as well as in the precursors themselves. Expression of Oligo2 in the spinal cord precedes that of platel...
متن کاملThe basic helix-loop-helix transcription factor NeuroD1 facilitates interaction of Sp1 with the secretin gene enhancer.
The basic helix-loop-helix transcription factor NeuroD1 is required for late events in neuronal differentiation, for maturation of pancreatic beta cells, and for terminal differentiation of enteroendocrine cells expressing the hormone secretin. NeuroD1-null mice demonstrated that this protein is essential for expression of the secretin gene in the murine intestine, and yet it is a relatively we...
