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

There is only one protein coding transcript and one polypeptide associated with this gene
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.
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).
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 testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
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.
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.
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.
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.
