==The Crystal Structure of Mouse Exo70 Reveals Unique Features of the Mammalian Exocyst==
-
The exocyst is a eukaryotic tethering complex necessary for the fusion of, exocytic vesicles with the plasma membrane. Its function in vivo is, tightly regulated by interactions with multiple small GTPases. Exo70, one, of the eight subunits of the exocyst, is important for the localization of, the exocyst to the plasma membrane. It interacts with TC10 and Rho3, GTPases in mammals and yeast, respectively, and has been shown recently to, bind to the actin-polymerization complex Arp2/3. Here, we present the, crystal structure of Mus musculus Exo70 at 2.25 A resolution. Exo70 is, composed of alpha-helices in a series of right-handed helix-turn-helix, motifs organized into a long rod of length 170 A and width 35 A. Although, the alpha-helical organization of this molecule is similar to that in, Saccharomyces cerevisiae Exo70, major structural differences are observed, on the surface of the molecule, at the domain boundaries, and in various, loop structures. In particular, the C-terminal domain of M. musculus Exo70, adopts a new orientation relative to the N-terminal half not seen in S., cerevisiae Exo70 structures. Given the low level of sequence conservation, within Exo70, this structure provides new insights into our understanding, of many species-specific functions of the exocyst.

== Function ==
 +
[https://www.uniprot.org/uniprot/EXOC7_MOUSE EXOC7_MOUSE] Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane. In adipocytes, plays a crucial role in targeting SLC2A4 vesicle to the plasma membrane in response to insulin, perhaps directing the vesicle to the precise site of fusion. It is required for neuron survival and plays an essential role in cortical development (By similarity).[UniProtKB:E7FC72]<ref>PMID:12687004</ref>
