Description:
The sterile alpha motif (SAM) domain is a protein interaction module that is present in diverse signal-transducing proteins. SAM domains are known to form homo- and hetero-oligomers. The crystal structure of the SAM domain from an Eph receptor tyrosine kinase, EphB2, reveals two large interfaces. In one interface, adjacent monomers exchange amino-terminal peptides that insert into a hydrophobic groove on each neighbor. A second interface is composed of the carboxyl-terminal helix and a nearby loop. A possible oligomer, constructed from a combination of these binding modes, may provide a platform for the formation of larger protein complexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thanos, C D -- Goodwill, K E -- Bowie, J U -- New York, N.Y. -- Science. 1999 Feb 5;283(5403):833-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UCLA-DOE Laboratory of Structural Biology and Molecular Medicine and Department of Chemistry and Biochemistry, University of California, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9933164" target="_blank"〉PubMed〈/a〉
