    6184   GTP Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of GTP Guanosine Triphosphate. 
    7017   Microtubule Based Process  Any Cellular Process That Depends Upon or Alters the Microtubule Cytoskeleton That Part of the Cytoskeleton Comprising Microtubules and Their Associated Proteins. 
    51258   Protein Polymerization  The Process of Creating Protein Polymers Compounds Composed of a Large Number of Component Monomers; Polymeric Proteins May Be Made Up of Different or Identical Monomers. Polymerization Occurs by the Addition of Extra Monomers to an Existing Poly or Oligomeric Protein. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5856   Cytoskeleton  Any of the Various Filamentous Elements That Form the Internal Framework of Cells and Typically Remain After Treatment of the Cells with Mild Detergent to Remove Membrane Constituents and Soluble Components of the Cytoplasm. the Term Embraces Intermediate Filaments Microfilaments Microtubules the Microtrabecular Lattice and Other Structures Characterized by a Polymeric Filamentous Nature and Long Range Order Within the Cell. the Various Elements of the Cytoskeleton Not Only Serve in the Maintenance of Cellular Shape But Also Have Roles in Other Cellular Functions Including Cellular Movement Cell Division Endocytosis and Movement of Organelles. 
    5874   Microtubule  Any of the Long Generally Straight Hollow Tubes of Internal Diameter 12 15 Nm and External Diameter 24 Nm Found in a Wide Variety of Eukaryotic Cells; Each Consists (usually) of 13 Protofilaments of Polymeric Tubulin Staggered in Such a Manner That the Tubulin Monomers Are Arranged in a Helical Pattern On the Microtubular Surface and with the Alpha/beta Axes of the Tubulin Subunits Parallel to the Long Axis of the Tubule; Exist in Equilibrium with Pool of Tubulin Monomers and Can Be Rapidly Assembled or Disassembled in Response to Physiological Stimuli; Concerned with Force Generation E.g. in the Spindle. 
    43234   Protein Complex  Any Macromolecular Complex Composed (only) of Two or More Polypeptide Subunits Along with Any Covalently Attached Molecules (such As Lipid Anchors or Oligosaccharide) or Non Protein Prosthetic Groups (such As Nucleotides or Metal Ions). Prosthetic Group in This Context Refers to a Tightly Bound Cofactor. the Component Polypeptide Subunits May Be Identical.
