Structures of Src-family tyrosine kinases
The crystal structures of three Src-family tyrosine kinases have been determined recently.
The structure of the catalytic domain of Lck has been determined in the active
autophosphorylated state. The structures of larger constructs of c-Src and Hck, containing
the SH3, SH2 and catalytic domains, as well as a C-terminal regulatory tail, have been
determined in the down-regulated state, phosphorylated in the C-terminal tail. A comparison
of these structures leads to an unanticipated mechanism for the regulation of catalytic activity …
