Disease relevance of nub

 

High impact information on nub

 

Biological context of nub

  • Together, these results suggest that previously characterized members of the embryonic regulatory hierarchy specify the patterns of the POU domain gene expression, which, in turn, function during neurogenesis and perhaps in earlier stages [7].
  • These POU domain genes, pdm-1 and pdm-2, are expressed at high levels during early embryogenesis and at lower levels throughout the rest of development [7].
  • The Drosophila POU domain transcriptional regulator, Drifter, is expressed in all cells within the wing pouch expressing a vgQ-lacZ transgene and is also excluded from the DV boundary [8].
  • Both the breathless gene, encoding a Drosophila fibroblast growth factor receptor tyrosine kinase homologue, and the POU-domain transcription factor gene, drifter, are expressed in all tracheal cells and are essential for directed cell migrations [9].
  • Cell lineage experiments in a nub mutant background show that clones respect neither the anterior-posterior nor the dorsal-ventral boundary but that the selector genes have been correctly expressed since early larval development [10].
 

Anatomical context of nub

  • Pdm and Castor specify late-born motor neuron identity in the NB7-1 lineage [11].
  • Function of the Drosophila POU domain transcription factor drifter as an upstream regulator of breathless receptor tyrosine kinase expression in developing trachea [9].
  • Ectopic expression of pdm-1 at the cellular blastoderm stage leads to disruptions in pair rule gene expression and in anterior segmentation [12].
  • The Drosophila drifter (dfr) gene, previously referred to as Cf1a, encodes a POU-domain DNA-binding protein implicated as a neuron-specific regulator in the developing central nervous system (CNS) [13].
  • Our study indicates that dpp is not the signal that dictates central pdm-1 repression across germ layers and suggests that in the same midgut region, different signalling pathways result in the differential activation or repression of potential transcription factors [14].
 

Associations of nub with chemical compounds

 

Physical interactions of nub

 

Other interactions of nub

  • We have characterized two Drosophila POU genes designated dPOU-19 and dPOU-28 [17].
  • By Northern analysis, all three of the genes are expressed in early embryos; the pdm-1 and Cf1a genes are also expressed at lower levels throughout development [18].
  • Specification of wing fate has been visualized by expression of the POU-homeodomain protein Nubbin in the presumptive wing territory and by repression of the homeodomain protein Homothorax [19].
  • Restricted patterning of vestigial expression in Drosophila wing imaginal discs requires synergistic activation by both Mad and the drifter POU domain transcription factor [8].
  • In spiders (terrestrial chelicerates), pdm/nubbin and apterous are expressed in successive segmental primordia that give rise to book lungs, lateral tubular tracheae, and spinnerets, novel structures that are used by spiders to breathe on land and to spin their webs [20].
