Oncogenic activation of tyrosine kinases

Curr Opin Genet Dev. 1994 Feb;4(1):15-24. doi: 10.1016/0959-437x(94)90086-8.


Tyrosine kinases comprise the largest group of oncoproteins, a fact that underscores the importance of reversible tyrosine phosphorylation in the regulation of essential cellular functions. Oncogenic activation of tyrosine kinases results in the constitutive activation of what is normally a conditionally regulated enzyme activity. Studies of tyrosine kinase oncoproteins, and a comparison with their corresponding proto-oncogene products, have identified important functional and regulatory domains within these proteins, positive and negative regulators of their enzyme activities and signalling cascades that control cell growth and differentiation.
