Molecular determinants of a regulatory prolyl isomerization in the signal adapter protein c-CrkII.

The cellular CT10 regulator of kinase protein (c-CrkII) transmits signals from oncogenic tyrosine kinases to cellular targets. Nuclear magnetic resonance studies had suggested that in chicken c-CrkII a native state prolyl cis-trans isomerization is involved in signal propagation. Corresponding evidence for the closely related human c-CrkII was not obtained… CONTINUE READING
