TAP 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. Belongs to the VDP/USO1/EDE1 family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
