No. 5 Group RAF effective squadrons of Bomber Command, personified by No 617 Squadron the "Dambusters", formed from 5 Group aircrew in March 1943. Most of the group's main airfields were around Lincoln, including RAF Scampton. By the end of the war the group had grown to 15 squadrons. The group was noted for its high accuracy bombing, being involved the sinking of the "Tirpitz" in November 1944 and the shattering of the strategic Bielefeld railway viaduct in March 1945. The Group introduced new weapons operationally, including Barnes Wallis's "bouncing" and his Tallboy and Grand Slam "earthquake" bombs. The group was disbanded on 15
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
