No. 617 Squadron RAF No. 617 Squadron RAF Number 617 Squadron is a Royal Air Force aircraft squadron, based at RAF Marham in Norfolk. It is commonly known as the "Dambusters", for its actions during Operation Chastise against German dams during the Second World War. In the early 21st century it operated the Tornado GR4 in the ground attack and reconnaissance role until being disbanded in the spring of 2014. The squadron reformed on 17 April 2018, and was equipped at RAF Marham during summer 2018 with the F-35 Lightning II, becoming the UK's first squadron with this advanced V/STOL type. According to the
C-Raf Kss1 in yeast) are activated by MEKK-related kinases (e.g. Ste11 in yeast) instead of Raf enzymes. Raf kinases found in retroviruses (such as murine v-Raf) are secondarily derived from the corresponding vertebrate genes of their hosts. These Raf genes encode severely truncated proteins, that lack the entire N-terminal autoinhibitory domain, and the 14-3-3 binding motifs. Such severe truncations are known to induce an uncontrolled activity of Raf kinases: that is just exactly what a virus may need for efficient reproduction. As mentioned above, the regulation of c-Raf activity is complex. As a "gatekeeper" of the ERK1/2 pathway, it is kept
