    Chain A
    GO ID   Ontology GO Term Definition
    16459   Myosin Complex  A Protein Complex Formed of One or More Myosin Heavy Chains Plus Associated Light Chains and Other Proteins That Functions As a Molecular Motor; Uses the Energy of ATP Hydrolysis to Move Actin Filaments or to Move Vesicles or Other Cargo On Fixed Actin Filaments; Has Magnesium Atpase Activity and Binds Actin. Myosin Classes Are Distinguished Based On Sequence Features of the Motor or Head Domain But Also Have Distinct Tail Regions That Are Believed to Bind Specific Cargoes. 
    3774   Motor Activity  Catalysis of the Generation of Force Resulting Either in Movement Along a Microfilament or Microtubule or in Torque Resulting in Membrane Scission Coupled to the Hydrolysis of a Nucleoside Triphosphate. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    Chain B
    GO ID   Ontology GO Term Definition
    72583   Clathrin Mediated Endocytosis  An Endocytosis Process That Begins When Material Is Taken Up Into Clathrin Coated Pits Which Then Pinch Off to Form Clathrin Coated Endocytic Vesicles. 
    3924   Gtpase Activity  Catalysis of the Reaction: GTP + H2o = GDP + Phosphate. 
    5525   GTP Binding  Interacting Selectively and Non Covalently with GTP Guanosine Triphosphate.
