Uso1_p115_C

Uso1_p115_C
PFAM accession number:PF04871
Interpro abstract (IPR006955): This domain identifies a group of proteins, which are described as: General vesicular transport factor, Transcytosis associate protein (TAP) and 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 [(PUBMED:11927603)]. 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 acidic C-terminal region, which binds to the golgins giantin and GM130. p115 is thought to juxtapose two membranes by binding giantin with one acidic region, and GM130 with another [(PUBMED:12077354)].
