    GO ID   Ontology GO Term Definition
    60315   Negative Regulation of Ryanodine Sensitive Calcium Release Channel Activity  Any Process That Decreases the Activity of a Ryanodine Sensitive Calcium Release Channel. the Ryanodine Sensitive Calcium Release Channel Catalyzes the Transmembrane Transfer of a Calcium Ion by a Channel That Opens When a Ryanodine Class Ligand Has Been Bound by the Channel Complex or One of Its Constituent Parts. 
    922   Spindle Pole  Either of the Ends of a Spindle Where Spindle Microtubules Are Organized; Usually Contains a Microtubule Organizing Center and Accessory Molecules Spindle Microtubules and Astral Microtubules. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5819   Spindle  The Array of Microtubules and Associated Molecules That Forms Between Opposite Poles of a Eukaryotic Cell During Mitosis or Meiosis and Serves to Move the Duplicated Chromosomes Apart. 
    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. 
    5509   Calcium Ion Binding  Interacting Selectively and Non Covalently with Calcium Ions (ca2+). 
    5515   Protein Binding  Interacting Selectively and Non Covalently with Any Protein or Protein Complex (a Complex of Two or More Proteins That May Include Other Nonprotein Molecules). 
    19904   Protein Domain Specific Binding  Interacting Selectively and Non Covalently with a Specific Domain of a Protein. 
    31432   Titin Binding  Interacting Selectively and Non Covalently with Titin Any of a Family of Giant Proteins Found in Striated and Smooth Muscle. in Striated Muscle Single Titin Molecules Span Half the Sarcomere with Their N and C Termini in the Z Disc and M Line Respectively. 
    31996   Thioesterase Binding  Interacting Selectively and Non Covalently with Any Thioesterase Enzyme. 
    31997   N Terminal Myristoylation Domain Binding  Interacting Selectively and Non Covalently with the N Terminus of a Protein That Has the Potential to Be or Has Been Modified by N Terminal Myristoylation. Binding Affinity Is Typically Altered by Myristoylation; For Example N Terminal Myristoylation of Hiv Nef Increases Its Affinity For Calmodulin. 
    43274   Phospholipase Binding  Interacting Selectively and Non Covalently with Any Phospholipase Enzymes That Catalyze of the Hydrolysis of a Glycerophospholipid. 
    44325   Ion Channel Binding  Interacting Selectively and Non Covalently with One or More Specific Sites On an Ion Channel a Protein Complex That Spans a Membrane and Forms a Water Filled Channel Across the Phospholipid Bilayer Allowing Selective Ion Transport Down Its Electrochemical Gradient. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
