|Other Names||General vesicular transport factor p115, Protein USO1 homolog, Transcytosis-associated protein, TAP, Vesicle-docking protein, USO1, VDP|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP14035b was selected from the C-term region of USO1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||General vesicular transport factor required for intercisternal transport in the Golgi stack; it is required for transcytotic fusion and/or subsequent binding of the vesicles to the target membrane. May well act as a vesicular anchor by interacting with the target membrane and holding the vesicular and target membranes in proximity.|
|Cellular Location||Cytoplasm, cytosol. Golgi apparatus membrane; Peripheral membrane protein Note=Recycles between the cytosol and the Golgi apparatus during interphase. During interphase, the phosphorylated form is found exclusively in cytosol; the unphosphorylated form is associated with Golgi apparatus membranes.|

The protein encoded by this gene is a peripheral membraneprotein which recycles between the cytosol and the Golgi apparatusduring interphase. It is regulated by phosphorylation:dephosphorylated protein associates with the Golgi membrane anddissociates from the membrane upon phosphorylation. Ras-associatedprotein 1 recruits this protein to coat protein complex II (COPII)vesicles during budding from the endoplasmic reticulum, where itinteracts with a set of COPII vesicle-associated SNAREs to form acis-SNARE complex that promotes targeting to the Golgi apparatus.Transport from the ER to the cis/medial Golgi compartments requiresthe action of this gene product, GM130 and giantin in a sequentialmanner.
