Phosphorylation of Groucho Mediates RTK Feedback Inhibition and Prolonged Pathway Target Gene Expression
BACKGROUND Signaling by receptor tyrosine kinase (RTK) pathways plays fundamental roles in processes of cell-fate determination, often through the induction of specific transcriptional responses. Yet it is not fully understood how continuous target gene expression, required for irreversible cell-fate specification, is preserved after RTK signaling has ended. Here we address this question using ...
متن کاملRTK/Ras/MAPK signaling.
Receptor Tyrosine Kinase (RTK)/Ras GTPase/MAP kinase (MAPK) signaling pathways are used repeatedly during metazoan development to control many different biological processes. In the nematode Caenorhabditis elegans, two different RTKs (LET-23/EGFR and EGL-15/FGFR) are known to stimulate LET-60/Ras and a MAPK cascade consisting of the kinases LIN-45/Raf, MEK-2/MEK and MPK-1/ERK. This Ras/MAPK cas...
متن کاملIonospheric Effects on Network-RTK
Ionospheric Effects on Network-RTK A part of the atmosphere is ionized by the UV radiation from the Sun. This part is often referred to as the ionosphere. The resulting free electrons influence the GNSS signals as they propagate through the ionosphere. We have studied how the spatial variations of electron density in the ionosphere affect measurements with network-RTK. The aim is to predict wha...
متن کاملA Novel Un-differenced PPP-RTK Concept
In this contribution, a novel un-differenced (UD) (PPP-RTK) concept, i.e. a synthesis of Precise Point Positioning and Network-based Real-Time Kinematic concept, is introduced. In the first step of our PPP-RTK approach, the UD GNSS observations from a regional reference network are processed based upon re-parameterised observation equations, corrections for satellite clocks, phase biases and (i...
متن کاملPrecise Real-Time Positioning Using Network RTK
In the classic RTK method using a single reference station the rover needs to work within a short range from the reference station due to the spatial decorrelation of distance-dependent errors induced by the ionosphere, troposphere and orbital errors. The operating range of RTK positioning is thus dependent on the existing atmospheric conditions and is usually limited to a distance of up to 10-...
