High impact information on dome

  • These data show that mom functions as a receptor of the Drosophila JAK/STAT signal transduction pathway [1].
  • We also show that dome functions downstream of upd and that both the extracellular and intracellular domains of Dome are required for JAK/STAT signaling [2].
  • We have isolated domeless (dome) in a screen to identify genes essential in epithelial morphogenesis during oogenesis [2].
  • In a genetic screen for novel genes controlling cell movement during posterior foregut development, we have identified and molecularly characterized two alleles of the domeless gene which encodes the Drosophila Janus kinase (JAK)/STAT receptor [3].
  • Upd regulates eye size through the Dome/Jak(Hop)/STAT92 signaling pathway to promote cell proliferation [4].

Biological context of dome

  • Altogether, our data indicate that Dome is an essential receptor molecule for Upd and JAK/STAT signaling during oogenesis [2].
  • Site-specific, high-affinity binding of C to its recognition sequence results in both axial and torsional distortion of DNA at P(mom), which appears to play a role in recruitment of RNA polymerase to the promoter for mom gene transactivation [5].

Anatomical context of dome

  • We demonstrate that mutants for domeless or any other known component of the canonical JAK/STAT signaling pathway display a failure of coordinated cell movement during the development of the proventriculus, a multiply folded organ which is formed by stereotyped cell rearrangements in the posterior foregut [3].
  • The Wg pathway in Drosophila is compared, first, to the Wnt pathway in dorsal mesoderm specification in Xenopus: second, to the same pathway in sea urchins; third, to the equivalent in the mom cascade of C. elegans; and finally, to parts of the equivalent pathway in Dictyostelium discoideum [6].
