15/p230 trans Golgi
The Golgi apparatus is a very complex and dynamic organelle that functions in protein sorting and modification. Numerous structural and regulatory proteins are involved in the budding, docking, and fusion of Golgi-directed vesicles. p230 trans Golgi is a peripheral membrane protein associated with the cytosolic face of the trans Golgi network (TGN). Protein sequence analysis indicates that it is highly hydrophilic and contains two proline-rich regions, as well as a high frequency of heptad repeats which are characteristic of α-helices that form dimeric coiled-coiled structures. Additionally, p230 trans Golgi contains a ESLALEELEL sequence, a motif of the acidic granin proteins that are found in secretory granules of neuroendocrine cells. p230 trans Golgi cycles between the cytosol and the TGN via non-clathrin coated vesicles in a G protein-dependent manner. The localization of p230 trans Golgi to the TGN is dependent on aromatic residues in its C-terminal non-coiled coil domain. Thus, p230 trans-Golgi is aTGN-specific protein that is important for the biogenesis of distinct populations of non-clathrin coated vesicles and, thus, functions in vesicular transport from the TGN.
This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.
