Structural highlights 2m0y is a 1 chain structure with sequence from Mus musculus. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Solution NMR Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function DOCK1_MOUSE Involved in cytoskeletal rearrangements required for phagocytosis of apoptotic cells and cell motility. Functions as a guanine nucleotide exchange factor (GEF), which activates Rac Rho small GTPases by exchanging bound GDP for free GTP. Its GEF activity may be enhanced by ELMO1 (By similarity). Publication Abstract from PubMed DOCK180 family proteins are Rho guanine nucleotide exchange factors (GEFs). DOCK1-5 contain an N-terminal SH3 domain implicated in their autoinhibition. Release of the closed conformation requires the interaction between SH3 and ELMO. Here we solved the solution structure of DOCK180 SH3 domain, which shares similar target binding features with the SH3 domain of DOCK2. The conserved N-terminal extension packs with the SH3 core domain and forms a new target binding site distinct from the canonical "PxxP" site. Our results demonstrate that the bidentate target binding mode of DOCK180 SH3 domain might be a general feature in all DOCK proteins. Proteins 2012. (c) 2012 Wiley Periodicals, Inc.
