Torso-like functions independently of Torso to regulate Drosophila growth and developmental timing.
Activation of the Drosophila receptor tyrosine kinase Torso (Tor) only at the termini of the embryo is achieved by the localized expression of the maternal gene Torso-like (Tsl). Tor has a second function in the prothoracic gland as the receptor for prothoracicotropic hormone (PTTH) that initiates metamorphosis. Consistent with the function of Tor in this tissue, Tsl also localizes to the proth...
متن کاملEffect of Torso
Most clinical ECG leads determine cardiac currents from a few surface potential samples, without quantitating torso geometry and structure, by empirical-intuitive methods. The present report is part of a broader study asking whether the known limitations of ECG can be reduced by multi-electrode grid leads which sample extensively, measure torso geometry and structure, and use clearly defined bi...
متن کاملReconstitution of Torso signaling in cultured cells suggests a role for both Trunk and Torso-like in receptor activation.
Formation of the Drosophila embryonic termini is controlled by the localized activation of the receptor tyrosine kinase Torso. Both Torso and Torso's presumed ligand, Trunk, are expressed uniformly in the early embryo. Polar activation of Torso requires Torso-like, which is expressed by follicle cells adjacent to the ends of the developing oocyte. We find that Torso expressed at high levels in ...
متن کاملDevelopmental Evolution: Torso — a Story with Different Ends?
The Torso pathway patterns the ends of the Drosophila embryo. Now, it has been found to control axis elongation in the short germ insect Tribolium. This result raises the issue of the ancestral function of the Torso pathway and its evolution.
متن کاملThe torso ligand, unmasked?
When a transmembrane receptor protein tyrosine kinase (RTK) is expressed throughout the plasma membrane, yet only a specific handful of them must be activated, what's a ligand to do? During the development of the anterior and posterior termini of the Drosophila embryo, uniformly secreted ligand precursors are activated by proteolysis near the location of the receptors that must be activated. St...
