Biophysical Studies of Eukaryotic Gene Regulation and Molecular Recognition 
via molecular recognition, including steroid- minations of these proteins will be pursued once 
binding proteins, polypeptide-binding proteins, they are fully characterized and suitable crystals 
and enzymes. Three-dimensional structure deter- and cocrystals become available. 
F-Actin 
Proposed model of the dystrophin-glycoprotein complex. Dystrophin dimers link the cyto- 
skeleton with the membrane glycoprotein complex by binding to actin at the amino ter- 
minus (N) and to the 50-, 43-, and 35-kDa transmembrane proteins at the carboxyl ter- 
minus (C).
