Vesicular transport adaptor protein

An overview of the trafficking of some adaptor protein (AP) complexes.
Adaptor Protein complexes and COPI-F subcomplex.[1]

Vesicular transport adaptor proteins are proteins involved in forming complexes that function in the trafficking of molecules from one subcellular location to another.[2][3][4] These complexes concentrate the correct cargo molecules in vesicles that bud or extrude off of one organelle and travel to another location, where the cargo is delivered. While some of the details of how these adaptor proteins achieve their trafficking specificity has been worked out, there is still much to be learned.

There are several human disorders associated with defects in components of these complexes[5][6] including Alzheimer's and Parkinson's diseases.[7]
