If it is correct that each golgin can bind multiple partners then careful analysis will be required to dissect the precise role of each interaction. However, one striking theme is that many golgins can bind to small GTPases. Amphiphysin, a dominant autoantigen in paraneoplastic Stiff-man syndrome, is a neuronal protein highly concentrated in nerve terminals. The function of synaptogyrin 1 is unknown. Schneider, The role of the nonneuronal splice-variants is less clear, and although originally reported to be on the Golgi, more recent reports have suggested that they are located to vesicle docking sites on the plasma membrane Ohara-Imaizumi et al.

AP A synaptic protein involved in clathrin mediated endocytosis General Information During neurotransmitter release synaptic vesicles fuse with the presynaptic plasma membrane. GRIP, the glutamate receptor interacting protein, is a post-synaptic scaffolding protein consisting of seven PDZ domains.

Like synaptophysin 1, synaptoporin is widely expressed in neurons and colocalizes with synaptophysin 1 on synaptic vesicles whereas panthophysin is expressed in all tissues.
PLoS Pathog. It is thought that the resulting fragmentation of the Golgi is required for the diversion of lipids and other nutrients into the replicative vacuole.

They may link Rab 6 mediated non-neuronal membrane traffic at the Golgi complex to neuronal membrane traffic at the active zone executed via RIMs.
This subunit contains a N-terminal cytoplasmic domain and a C-terminal transmembrane domain with probably 6 transmembrane regions. Vacuolar proton pump kDa subunit Largest subunit of the vacuolar proton pump in synaptic vesicles and coated vesicles General Information The vacuolar proton pump is involved in the acidification of many intracellular organelles.

|The fact that GFP foci depend upon the presence of an interacting protein fused to Vps32 argues that the Vps32 fusion protein targets the GFP fusion protein to the endosome.
Synaptoporin Synaptophysin 2 Synaptic vesicle membrane protein similar to synaptophysin 1 General Information Synaptoporin, also known as synaptophysin 2, is highly homologous to synaptophysin 1 but encoded by a different gene.
It is well conserved in evolution with a single ortholog in all metazoans so far examined as well as in fungi, plants and Dictyostelium Fridmann-Sirkis et al. Radinovic, M. Their significance is unclear, and may be difficult to address, but at the very least, they are relevant to the study of GM function in primate cell lines. The C terminus of Munc interacts directly with a putative coiled coil domain in the N-terminal part of syntaxin.

Two splice variants of ERC 1 1a and 1b have been described. Clathrin consists of heavy chains and light chains that co-assemble to triskelions. Kalachikov, R. Clathrin coated vesicles are involved in a wide variety of transport events of the eucaryotic cell.
Like synaptophysin, synaptogyrin 1 has four transmembrane domains and an extended cytoplasmic tail but it is not glycosylated. The fact that GFP foci depend upon the presence of an interacting protein fused to Vps32 argues that the Vps32 fusion protein targets the GFP fusion protein to the endosome.

It is thus an excellent marker for subsets of synapses. A peripheral protein associated with the cis-Golgi network redistributes in the intermediate compartment upon brefeldin A treatment. However, it seems unlikely that GM is essential for membrane traffic as a mutant Chinese hamster cell line has been identified that lacks detectable GM and although temperature sensitive, it shows no defects in Golgi structure or protein transport at the permissive temperature Vasile et al.
In addition, studies with knockout mice or human genetic diseases have shown that loss of the apparently ubiquitously expressed golgins GMAP, TMF, or golgin results in tissue-specific defects rather than cell lethality. Michaelis and A.
