Protein
AP-1 complex subunit mu-2
Organism
Arabidopsis thaliana
Function
Subunit of clathrin-associated adaptor protein complex 1 that plays a role in protein sorting at the trans-Golgi network and early endosomes (TGN/EE). The AP complexes mediate the recruitment of clathrin to membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules. Required for KNOLLE localization at the cell plate to mediate cytokinesis. Functions redundantly with AP1M1 in multiple post-Golgi trafficking pathways leading from the TGN to the vacuole, the plasma membrane, and the cell-division plane.
Similarity
Belongs to the adaptor complexes medium subunit family.
