機能Subunit of clathrin-associated adaptor protein complex 1 that plays a role in protein sorting in the trans-Golgi network (TGN) and endosomes. The AP complexes mediate the recruitment of clathrin to membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules.
配列類似性Belongs to the adaptor complexes medium subunit family. Contains 1 MHD (mu homology) domain.
翻訳後修飾Phosphorylation of membrane-bound AP1M1/AP1M2 increases its affinity for sorting signals.
細胞内局在Golgi apparatus. Cytoplasmic vesicle > clathrin-coated vesicle membrane. Component of the coat surrounding the cytoplasmic face of coated vesicles located at the Golgi complex.
