OTHER DNA BINDING DOMAIN TRANSCRIPTION FACTORS -
The Other DNA binding domain transcription factors group is a collection of DNA-binding transcription factors that do not fit into any of the other major domain-based transcription factor groups.
UniProt Contributed Function Data
May negatively regulate Notch-induced cell proliferation in the eye-head primordium. May act in leg and wing primordia to negatively regulate body-wall specifying genes and thereby promote appendage formation. Required for tracheal development.

    The noc and elB paralogs interact with hth to correctly specify the photoreceptors which detect polarised light at the dorsal rim of the retina, being involved in specifying both morphological and molecular fate. noc and elB also antagonise the transcriptional activator and repressor functions of oc in the retina through distinct protein domains.
    Loss of elB and noc activities induce extensive outgrowths, in a N-dependent way. These overgrowths are not linked to ectopic production of os.
    elB appears, with noc, to regulate the growth of the highly proliferative tissue of the eye-head primordium.
    Identification: screen for mutants in opsin regulation and photoreceptor cell type specification.
    Regulator of inner photoreceptor opsin genes.
    elB over-expression nearly perfectly mimics the loss-of-function phenotype of oc, one of the few mutants known to affect opsin regulation.
    The elbow locus is made up of two genes, elA and elB, each of which has a distinct phenotype when mutant. Mutations in elA have a strong phenotype with marked disruptions of the wing. Mutations in elB are weak, mainly affecting the alula and wing bristles. elA and elB are dominant enhancers of each other.
    Part of the "elbow-noc" complex.
    Wings extended and bent backward, often warped and shortened; sometimes blistered and nicked. Alulae reduced in size with reduced number of marginal bristles -- may fuse with wing blade. Venation reduced by terminal shortening of L5 and of crossveins. Halteres reduced, often to stubs. Eye size decreased (variable, even with strong alleles). Weak alleles may overlap wild type and show only a reduction in number of marginal bristles on alulae. Some alleles may be semi-lethal when hemizygous. Class (i) alleles enhance nocSco, are semi-lethal with 35Ba alleles of noc and show a weak noc phenotype when heterozygous with strong noc alleles or noc deletions. Class (ii) alleles do not interact with these loci. All alleles more extreme when hemizygous; strong alleles nearly apterous.
