    basic FUNCTION
  • heterotetrameric adaptor complex AP-1 with AP1G, AP1M1/M2, AP1S1/2 transporting ligand receptor complexes from transGolgi network to lysosome
  • playing a a critical role in development of the skin and spinal cord (Montpetit 2008)
  • regulate clathrin-coated vesicle assembly, protein cargo sorting, and vesicular trafficking between organelles in eukaryotic cells (Montpetit 2008)
  • AP1S1 complex mediates protein sorting between the trans-Golgi network and early endosomes
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS endocytosis transport , cellular trafficking transport
    PATHWAY
    metabolism
    signaling
    a component
  • part of the clathrin coat assembly complex which links clathrin to receptors in coated vesicles
  • heterotetrameric adaptor complex AP-1 with AP1G, AP1M1/M2, AP1S1/2
