ity.18,19 The Abl SH2 domain forms an extensive interaction interface with the C-terminal lobe of the kinase domain that is stabilized by an interlocking network of hydrogen bonds (Fig. 2).18 Due to the different relative orientation of the 2 kinase lobes in Src and Abl, the SH2 domain approaches the kinase domain much closer in Abl (Fig. 2). The SH2âC-
Tyrosine kinase. A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to a protein in a cell. It functions as an on or off switch in many cellular functions. Tyrosine kinases are a subclass of protein kinase. The phosphate group is attached to the amino acid tyrosine on the protein.
