basic helix-loop-helix (bHLH) domain found in Drosophila melanogaster protein daughterless (Da) and similar proteins; Da is a nuclear bHLH transcription factor that is a sole E protein ortholog essential for both neurogenesis and sex determination in Drosophila. Da is expressed in a broad range of tissues and is involved in diverse developmental processes such as oogenesis, sex determination and neurogenesis depending on its bHLH-binding partners. Da and achaete-scute complex (AS-C) form heterodimers that act as transcriptional activators of neural cell fates and are involved in sex determination.

basic helix-loop-helix (bHLH) domain found in E proteins family; The E proteins family corresponds to class I bHLH proteins, which are widely expressed within the immune system and on which the majority of this chapter will be focused. Members in this family include E2A (also referred to as TCF-3), E47, TCF-12 (also referred to as HEB), and TCF-4 (also referred to as E2-2) in vertebrates, as well as the E protein ortholog, Daughterless (Da), from Drosophila melanogaster. E-proteins are expressed broadly and in certain complexes they are restricted to specific cell types. E-proteins homodimerize and heterodimerize with the tissue specific bHLH factors to bind DNA and regulate transcription and differentiation of cells during development. The activity of the E-proteins is regulated by two main mechanisms: first, the relative concentrations of E-proteins, tissue specific bHLH factors, and the Id proteins, and second, covalent modification.

576-622 1.83e-07

basic Helix Loop Helix (bHLH) domain superfamily; bHLH proteins are transcriptional regulators that are found in organisms from yeast to humans. Members of the bHLH superfamily have two highly conserved and functionally distinct regions. The basic part is at the amino end of the bHLH that may bind DNA to a consensus hexanucleotide sequence known as the E box (CANNTG). Different families of bHLH proteins recognize different E-box consensus sequences. At the carboxyl-terminal end of the region is the HLH region that interacts with other proteins to form homo- and heterodimers. bHLH proteins function as a diverse set of regulatory factors because they recognize different DNA sequences and dimerize with different proteins. The bHLH proteins can be divided to cell-type specific and widely expressed proteins. The cell-type specific members of bHLH superfamily are involved in cell-fate determination and act in neurogenesis, cardiogenesis, myogenesis, and hematopoiesis.

It is essential for primordial follicle formation and expression of many genes required for folliculogenesis, fertilization and early embryonic survival. FIGLA knockout mice cannot form primordial follicles and lose oocytes rapidly after birth, whereas male gonads are unaffected.

MGA, also termed MAX dimerization protein 5 (MAD5), is a dual specificity T-box/ bHLHzip transcription factor that regulates the expression of both Max-network and T-box family target genes. It contains a Myc-like bHLHZip motif and requires heterodimerization with Max for binding to the preferred Myc-Max-binding site CACGTG. In addition to the bHLHZip domain, MGA harbors a second DNA-binding domain, the T-box or T-domain. It thus binds the preferred Brachyury-binding sequence and represses transcription of reporter genes containing promoter-proximal Brachyury-binding sites. spESC1 is a bHLHzip protein with homology to human MyoD and Myf-5 myogenic differentiation inducers. It is involved in the sexual differentiation process.

basic Helix-Loop-Helix-zipper (bHLHzip) domain found in USF/MITF family; The USF (upstream stimulatory factor)/MITF (microphthalmia-associated transcription factor) family includes two bHLHzip transcription factor subfamilies. USFs are ubiquitously expressed and key regulators of a wide number of gene regulation networks, including the stress and immune responses, cell cycle and proliferation, lipid and glucid metabolism. USFs recruit chromatin remodeling enzymes and interact with co-activators and the members of the transcription pre-initiation complex. USFs interact with high affinity to E-box regulatory elements. The MITF (also known as microphthalmia-TFE, or MiT) subfamily comprises four genes in mammals (MITF, TFE3, TFEB, and TFEC); each gene has different functions. MITF is involved in neural crest melanocytes development as well as the pigmented retinal epithelium. TFEB is required for vascularization of the mouse placenta. TFE3 is involved in B cell function. TFEC regulates gene expression in macrophages. The MITF subfamily proteins can form homodimers or heterodimers with each other but not with other bHLH or bHLHzip proteins.
