The Src homology domains, SH3 and SH2, of Abl protein tyrosine kinase regulate enzymatic activity in vivo. Abl SH3 suppresses kinase activity, whereas Abl SH2 is required for the transforming activity of the activated form of Abl. We expect that the solution structures of Abl SH3, Abl SH2 and Abl SH(32) (a dual domain comprising SH3 and SH2 subdomains) will contribute to a structural basis for understanding the mechanism of the Abl 'regulatory apparatus'.
