      Detailed Description
      Statement
      Reference

      Mutant clones show cell autonomous outgrowths similar to those caused by brkM68 clones. Outgrowths are often accompanied by notches. Detailed examination of the outgrowths suggests that loss of brk produces a lower level of activation than that caused by constitutively activated tkv.

      (Jazwinska et al., 1999)

      Scer\FLP1 induced clones of tkvQ253D.Ubx expressing cells result in the formation of ectopic veins.
