Receptor signalling: To Sevenless, a daughter
Genetic studies with Drosophila identified what appeared to be a linear signalling cassette connecting extracellular signals to nuclear responses. But the discovery of a substrate for the Sevenless receptor indicates that the concept of a single, linear pathway may be an oversimplification.
متن کاملDaughter of Sevenless Is a Substrate of the Phosphotyrosine Phosphatase Corkscrew and Functions during Sevenless Signaling
The SH2 domain-containing phosphotyrosine phosphatase Corkscrew (CSW) is an essential component of the signaling pathway initiated by the activation of the sevenless receptor tyrosine kinase (SEV) during Drosophila eye development. We have used genetic and biochemical approaches to identify a substrate for CSW. Expression of a catalytically inactive CSW was used to trap CSW in a complex with a ...
متن کاملIn vivo functional analysis of the Daughter of Sevenless protein in receptor tyrosine kinase signaling
One mechanism used by receptor tyrosine kinases to relay a signal to different downstream effector molecules is to use adaptor proteins that provide docking sites for a variety of proteins. The daughter of sevenless (dos) gene was isolated in a genetic screen for components acting downstream of the Sevenless (Sev) receptor tyrosine kinase. Dos contains a N-terminally located PH domain and sever...
متن کاملThe sevenless signalling cassette mediates Drosophila EGF receptor function during epidermal development.
In Drosophila, Drk, an SH2 adaptor protein, Sos, a putative activator of Ras1, Ras1, raf and rolled/MAP kinase have been shown to be required for signalling from the sevenless and the torso receptor tyrosine kinase. From these studies, it was unclear whether these components act in a single linear pathway as suggested by the genetic analysis or whether different components serve to integrate di...
متن کاملApoptosis: from Signalling Pathways to Therapeutic Tools
Apoptosis or programmed cell death is a gene regulated phenomenon which is important in both physiological and pathological conditions. It is characterized by distinct morphological features including chromatin condensation, cell and nuclear shrinkage, membrane blebbing and oligonucleosomal DNA fragmentation. Although, two major apoptotic pathways including 1) the death receptor (extrinsic) and...
