Protein
Vacuolar protein sorting-associated protein 26
Organism
Drosophila melanogaster
Function
Component of the retromer complex which acts in conjunction with wingless (wg) and clathrin-mediated endocytosis to sustain a wntless (wls) traffic loop. This loop encompasses the Golgi, the cell surface, an endocytic compartment and a retrograde route leading back to the Golgi, thereby enabling wls to direct wg secretion. The hh and dpp signaling pathways do not require the retromer complex suggesting that it does not play a general role in exocytosis.
Similarity
Belongs to the VPS26 family.
