Gene Summary
Transcriptional repressor of genes that require a bHLH protein for their transcription (PubMed:24618901). May serve as a transcriptional regulator of the Achaete-scute complex (AS-C) genes (PubMed:1528887). Contributes to the neural-epidermal lineage decision during early neurogenesis (PubMed:1427040). Part of the Notch signaling pathway, plays a role in neuroblasts proliferation in embryos and larvae (PubMed:10790334, PubMed:22357926). In the larval brain, together with other self-renewal transcriptional repressors such as klu and dpn, required for type II neuroblast self-renewal and for maintaining erm in an inactive state in intermediate neural progenitors (INP) derived from type II neuroblasts (PubMed:24618901).

ENHANCER OF SPLIT GENE COMPLEX -
The Enhancer of split complex (E(spl)-C) of D.mel is a well characterized genetic locus on chromosome 3R containing 12 genes - with the exception of Kaz-m1, all are Notch responsive. Seven genes are basic helix-loop-helix (bHLH) transcription factors, four are bearded family genes. Kaz-m1 is unrelated, sharing some sequence similarity to Kazal class protease inhibitors. (Adapted from FBrf0211195).
BASIC HELIX-LOOP-HELIX TRANSCRIPTION FACTORS -
Basic helix-loop-helix (bHLH) transcription factors are sequence-specific DNA-binding proteins that regulate transcription. They are characterized by a 60 amino acid region comprising a basic DNA binding domain followed by a HLH motif formed from two amphipathic α-helices connected by a loop. bHLH transcription factors form homo- and hetero-dimeric complexes, which bind to a E box consensus sequence. (Adapted from PMID:15186484).
Protein Function (UniProtKB)
Transcriptional repressor of genes that require a bHLH protein for their transcription (PubMed:24618901). May serve as a transcriptional regulator of the Achaete-scute complex (AS-C) genes (PubMed:1528887). Contributes to the neural-epidermal lineage decision during early neurogenesis (PubMed:1427040). Part of the Notch signaling pathway, plays a role in neuroblasts proliferation in embryos and larvae (PubMed:10790334, PubMed:22357926). In the larval brain, together with other self-renewal transcriptional repressors such as klu and dpn, required for type II neuroblast self-renewal and for maintaining erm in an inactive state in intermediate neural progenitors (INP) derived from type II neuroblasts (PubMed:24618901).

  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Comments

The predicted protein products of the seven HLH

genes in the E(spl) complex exhibit a great degree of sequence

similarity extending over the first 120 amino acids of the proteins. The

carboxy terminus is unique for each except for the terminal 4 amino acids,

which are identical in all of the proteins.

External Data
Subunit Structure (UniProtKB)

Homodimer (PubMed:22357926). Heterodimer with dpn (PubMed:22357926). Might form higher-order oligomers (PubMed:22357926). Transcription repression requires formation of a complex with a corepressor protein (Groucho) (By similarity).

(UniProt, Q01070)
Domain

Has a particular type of basic domain (presence of a helix-interrupting proline) that binds to the N-box (CACNAG), rather than the canonical E-box (CANNTG).

The C-terminal WRPW motif is a transcriptional repression domain necessary for the interaction with Groucho, a transcriptional corepressor recruited to specific target DNA by Hairy-related proteins.

        The distinct expression patterns of genes of the E(spl) complex in imaginal tissues depend to a significant degree on the capacity of their transcriptional cis-regulatory apparatus to respond selectively to direct proneural and Su(H)-mediated activation, often in a subset of the territories and cells in which proneural and Su(H) regulation is occurring. The m4 and HLHmγ enhancers are distinctly similar though the genes are expressed in dissimilar patterns in the wing disc. The HLHmγ enhancer shows a selective response to the N signalling pathway.

        N-inducible expression of HLHmδ and HLHmγ both in cultured cells and in vivo is dependent on functional Su(H) protein.

        The bHLH domains of the gene products encoded by the E(spl)-C and AS-C differ in their ability to form homo- and/or heterodimers. The interactions established through the bHLH link the products of the two complexes in a single interaction network which may function to ensure that a given cell retains the capacity to choose between epidermoblast and neuroblast fates until the cell becomes definitively determined.

        Clones mutant for E(spl)-C bHLH-encoding genes or for gro display bristle hyperplasia. The E(spl)-C genes participate in the N signalling pathway. E(spl)-C mutants are epistatic over a gain of function mutant of N and ac-sc mutants are epistatic over E(spl)-C mutants.

        The expression pattern of proneural genes of the AS-C and neurogenic genes of the E(spl)-C are examined in the procephlon and a map of the cells is constructed.

        Almost all E(spl)-complex bHLH proteins can homo-hetero-dimerise, but not with the same efficiency. All E(spl)-complex bHLH proteins interact with gro protein via their C-terminal domain. E(spl)-complex bHLH proteins interact with proneural proteins, with members of the E(spl) family exhibiting distinct preferences for different proneural proteins.

        The bristle loss phenotype of H mutants can be suppressed by deleting components of the E(spl)-complex. The degree of suppression depends on both the number and identity of E(spl)-complex transcription units removed.

        Gel retardation experiments demonstrate the 5' regulatory region contains putative in vitro binding sites for Su(H).

        Arrangement and sequence of E(spl)-complex genes in D.melanogaster and D.hydei revealed that the E(spl)-gene, and the structure of complex are highly conserved, suggesting that each individual gene, as well as the organization of the complex, is of functional importance.

        E(spl) region gene encoding HLH protein identified by low stringency hybridization to previously defined HLHm5 and HLHm7 probes. On basis of cross-hybridization and sequence data the E(spl) HLH genes can be placed into 3 groups. The first includes E(spl) and HLHm5, the second includes HLHm7, HLHm3, HLHmA and HLHmB and the last includes HLHmC.

        Direction of transcription of HLHmγ reported is at odds with that reported in Delidakis et al., PNAS 89:8731--8735 .

        Molecular analysis established identity of HLHmβ, HLHmγ and HLHmδ with HLHmA, HLHmB and HLHmC of Delidakis et al., respectively. HLHm3, HLHmβ, HLHmγ and HLHmδ encode helix-loop-helix proteins, bringing the total of such proteins in the E(spl) complex to seven.

        Genes of the E(spl) complex act as a functional unit composed of redundant genes which can partially substitute for each other. Eight E(spl)-region genes are required for the development of neurectodermal cells: HLHmδ, HLHmβ, HLHmγ, HLHm3, HLHm5, HLHm7, E(spl) and gro. The E(spl)-region gene m4 may also play a role in this process.

          GenBank Protein - A collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB.
          RefSeq - A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein.
          UniProt/GCRP - The gene-centric reference proteome (GCRP) provides a 1:1 mapping between genes and UniProt accessions in which a single 'canonical' isoform represents the product(s) of each protein-coding gene.
          UniProt/Swiss-Prot - Manually annotated and reviewed records of protein sequence and functional information
