Nature, 385:602-609, 1997 Cited by PubMed Abstract: The crystal structure of the haematopoietic cell kinase Hck has been determined at 2.6/2.9 A resolution. Inhibition of enzymatic activity is a consequence of intramolecular interactions of the enzyme's Src-homology domains SH2 and SH3, with concomitant displacement of elements of the catalytic domain. The conformation of the active site has similarities with that of inactive cyclin-dependent protein kinases. PubMed: 9024658 DOI: 10.1038/385602a0 PDB entries with the same primary citation
