%T The SH3 domain of Eps8 exists as a novel intertwined dimer.
%X SH3 domains are structurally well-characterized as monomeric modular units of protein structure that mediate protein-protein recognition in numerous signal transduction proteins. The X-ray crystallographic structure of the Eps8 SH3 domain reveals a novel variation of the canonical SH3 fold: the SH3 domain from Eps8 is a dimer formed by strand interchange. In addition, co-immunoprecipitation experiments show that intact Eps8 is multimeric in vivo. Hence, the SH3 domain of Eps8 may represent a dimerization motif.
