Cdc42-dependent nuclear translocation of non-receptor tyrosine kinase, ACK.

Ras signals for the transformation of mammalian cells are apparently transduced through Rho GTPases. The Rho GTPase family member Cdc42 generates independent signals that regulate the rearrangement of the actin cytoskeleton and the transcription of genes. However, the molecular mechanism of signal transduction from Cdc42 to the nucleus remains to be understood.
