Compositions and methods for inhibiting the growth of cancer cells are provided. The cancer cells, the growth of which is inhibited, have constitutively active Abl tyrosine kinase activity due to a t(9;22)(q34;q11) translocation which results in expression of a chimeric Bcr-Abl protein which has constitutively active Abl tyrosine kinase activity that is believed to play an important role in leukemogenesis. The compositions include a modified protein kinase C(PKC) which has an Abl tyrosine kinase target motif. The methods involve administering the modified PCK to an individual to inhibit the growth of cancer cells that have Abl tyrosine kinase activity. |
