In the present study , 1 discovered that dithreonine residues ( Thr 15 and Thr 16 ) at the intravesicular domain of mouse Syt 1 are post translationally modified by a complex form of O linked sugar ( i . e . the addition of sialic acids ) in PC 12 cells and that the O glycosylation of Syt 1 in COS 7 cells depends on the coexpression of vesicle associated membrane protein 2 ( VAMP 2 ) / synaptobrevin . 1 also showed that a transmembrane domain of Syt 1 directly interacts with isolated VAMP 2 , but not VAMP 2 , in the heterotrimeric SNARE ( SNAP receptor ) complex ( vesicle SNARE , VAMP 2 , and two target SNAREs , syntaxin IA and SNAP 25 ) . 0.68936483^^^

Synaptotagmin 1 , vamp 2 , and synapsin 1 proteins are synthesized at nearly constant rates as the neurons develop . ^^^ Despite the nearly constant rates of synthesis of synaptotagmin 1 , vamp 2 , and synapsin 1 , we show that the number of SVs in these developing neurons increases , and that SV proteins are more efficiently targeted to SVs at later times in culture . ^^^

The effect of SypI on VAMP 2 sorting was dose dependent , being reversed by increasing VAMP 2 expression levels , and highly specific , because the sorting of the SV proteins VAMP 1 and SytI was not affected by SypI . ^^^

In neurons the core SNARE ( soluble N ethylmaleimide sensitive factor attachment protein receptor ) complex , composed of syntaxin ( Stx ) , SNAP 25 , and VAMP 2 , mediates vesicle fusion , whereas calcium regulation is thought to be accomplished by the synaptotagmin ( Syt ) family , some of which exhibit calcium dependent binding to syntaxin and SNAP 25 . ^^^

Here we present several lines of evidence showing that the Syt 4 protein in PC 12 cells is normally localized in the Golgi or immature vesicles at the cell periphery and is sorted to fusion competent mature dense core vesicles in response to short nerve growth factor ( NGF ) stimulation . ( 1 ) In undifferentiated PC 12 cells , Syt 4 protein is mainly localized in the Golgi and small amounts are also present at the cell periphery , but according to the results of an immunocytochemical analysis , they do not colocalize with conventional secretory vesicle markers ( Syt 1 , Syt 9 , Rab3A , Rab27A , vesicle associated membrane protein 2 , and synaptophysin ) at all . ^^^

Synaptotagmin 1 , synaptobrevin 2 , and syntaxin 1 are coexpressed in rat and gerbil pinealocytes . ^^^ Antibodies against synaptotagmin 1 , synaptobrevin 2 , and syntaxin 1 label pinealocytes ( identified with an antiserum directed against synaptophysin 1 ) in pineal glands of both species , the coexpression of the latter proteins being demonstrable at the single cell level . ^^^ Immunogold staining has been performed in the gerbil pineal and reveals that synaptobrevin 2 and synaptotagmin 1 can be localized to the synaptic like microvesicles that are concentrated in pinealocyte process terminals . ^^^

Using indirect immunofluorescence combined with confocal laser scanning microscopy , it was observed that antisera against integral synaptic vesicle membrane proteins ( SV 2 , synaptotagmin 1 , synaptobrevin 2 and synaptophysin ) induced strong immunoreactivities in these cells , but anti synaptobrevin 1 caused only a faint fluorescence . ^^^

Labeling of synaptic vesicles prepared from adult brain with [ 3H ] palmitate revealed synaptobrevin 2 besides synaptotagmin 1 as major palmitoylated proteins . [ 3H ] Palmitoylation of synaptobrevin 2 was resistant to chloroform / methanol extraction , but sensitive to reducing agents indicating a covalent fatty acid bond to cysteine residues . ^^^
