Many mutations in receptor kinases that lead to cancer allow the dimerization and activation of the receptor, even in the absence of signaling molecule. An example of this is a mutant form of the EGF receptor kinase called Her2/neu

Her2/neu receptor kinases is being tested for its effectiveness in stopping cancer. At which
stage would this drug work?
A. It would prevent the signaling cell from
producing the signal.
B. It would prevent the receptor from binding
to the signal.
C. It would prevent the receptor from
