This domain identifies a group of proteins, which are described as: General vesicular transport factor, Transcytosis associated protein (TAP) or Vesicle docking protein, this myosin-shaped molecule consists of an N-terminal globular head region, a coiled-coil tail which mediates dimerisation, and a short C-terminal acidic region [<cite idref="PUB00008680"/>]. p115 tethers COP1 vesicles to the Golgi by binding the coiled coil proteins giantin (on the vesicles) and GM130 (on the Golgi), via its C-terminal acidic region. It is required for intercisternal transport in the Golgi stack. This domain is found in the head region. The head region is highly conserved, but its function is unknown. It does not seem to be essential for vesicle tethering [<cite idref="PUB00008680"/>]. The N-terminal part of the head region contains context-detected Armadillo/beta-catenin-like repeats.
