  Domain Name: Sec23-like
Sec23-like: Protein and membrane traffic in eukaryotes is mediated by at least in part by the budding and fusion of intracellular transport vesicles that selectively carry cargo proteins and lipids from donor to acceptor organelles. The two main classes of vesicular carriers within the endocytic and the biosynthetic pathways are COP- and clathrin-coated vesicles. Formation of COPII vesicles requires the ordered assembly of the coat built from several cytosolic components GTPase Sar1, complexes of Sec23-Sec24 and Sec13-Sec31. The process is initiated by the conversion of GDP to GTP by the GTPase Sar1 which then recruits the heterodimeric complex of Sec23 and Sec24. This heterodimeric complex generates the pre-budding complex. The final step leading to membrane deformation and budding of COPII-coated vesicles is carried by the heterodimeric complex Sec13-Sec31. The members of this CD belong to the Sec23-like family. Sec 23 is very similar to Sec24. The Sec23 and Sec24 polypeptides fold into five distinct domains: a beta-barrel, a zinc finger, a vWA or trunk, an all helical region and a carboxy Gelsolin domain. The members of this subgroup lack the consensus MIDAS motif but have the overall Para-Rossmann type fold that is characteristic of this superfamily.
No pairwise interactions are available for this conserved domain.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
