Hedgehog signaling and Tre1 regulate actin dynamics through PI(4,5)P2 to direct migration of Drosophila embryonic germ cells.
Title: Hedgehog signaling and Tre1 regulate actin dynamics through PI(4,5)P(2) to direct migration of Drosophila embryonic germ cells.
The authors uncovered a novel role for Rho-like signaling through the G protein-coupled receptor Tre1, a gene previously implicated in the trans-epithelial migration of germ cells.
Title: Drosophila immune cells extravasate from vessels to wounds using Tre1 GPCR and Rho signaling.
Bifurcation of the Tre1 G protein-coupled receptor signaling response via G protein-dependent and independent branches enables distinct spatiotemporal regulation of germ cell migration.
Title: Domain-specific control of germ cell polarity and migration by multifunction Tre1 GPCR.
feminizing the Tre1-expressing neurons in male flies leads to rapid courtship initiation, a phenotype that leads to increased reproductive success; Tre1 is expressed in a sexually dimorphic pattern in olfactory sensory neurons and the central nervous system
Title: A Novel Gene Controlling the Timing of Courtship Initiation in Drosophila melanogaster.
role of the arginine of the NRY motif in Tre1 was investigated; results suggest that a salt bridge may form between this critical arginine and an aspartic acid in transmembrane alpha-helix (TM6)in Tre1
Title: Molecular dynamics simulations on the Tre1 G protein-coupled receptor: exploring the role of the arginine of the NRY motif in Tre1 structure.
The scattershot allele results in an in-frame deletion of 8 amino acids at the junction of the third transmembrane domain and the second intracellular loop of Tre1 that dramatically impairs the function of this GPCR in germ cell migration.
Title: An evolutionarily conserved arginine is essential for Tre1 G protein-coupled receptor function during germ cell migration in Drosophila melanogaster.
plays an important role in regulation of germ cell migration, polarity , cell adhesion, and cadherin binding. (review)
Title: [New insights into cell migration from Drosophila germ cell migration].
Down-regulation of E-cadherin causes germ cell dispersal but is not sufficient for transepithelial migration in the absence of Tre1, suggesting a new mechanism for Tre1 GPCR function that links cell polarity, modulation of cell adhesion, and invasion.
