High resolution crystal structures of the p120 RasGAP SH3 domain.
B.Ross, O.Kristensen, D.Favre, J.Walicki, J.S.Kastrup, C.Widmann, M.Gajhede.
X-ray structures of two crystal forms of the Src homology 3 domain (SH3) of the Ras GTPase activating protein (RasGAP) were determined at 1.5 and 1.8A resolution. The overall structure comprises a single domain with two tightly packed beta-sheets linked by a short helical segment. An important motif for peptide binding in other SH3 domains is not conserved in RasGAP. The RasGAP SH3 domain forms dimers in the crystal structures, which may provide new functional insight. The dimer interface involves residues also present in a peptide previously identified as an apoptotic sensitizer of tumor cells.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
