AP180, or Synaptosome associated protein 91kDa, is a human gene encoded by SNAP91. It may also be known as: Clathrin coat assembly protein AP180; Clathrin coat-associated protein AP180; Phosphoprotein F1-20; 91 kDa synaptosomal-associated protein; synaptosomal-associated protein, 91kDa. The encoded protein has an amino acid length of 907 and a mass of 92.5 kDa. AP180 is a member of the PICALM/SNAP91 family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog.
