    GO ID   Ontology GO Term Definition
    14809   Regulation of Skeletal Muscle Contraction by Regulation of Release of Sequestered Calcium Ion  Any Process That Modulates the Frequency Rate or Extent of Skeletal Muscle Contraction Via the Regulation of the Release of Sequestered Calcium Ion by Sarcoplasmic Reticulum Into Cytosol. the Sarcoplasmic Reticulum Is the Endoplasmic Reticulum of Striated Muscle Specialised For the Sequestration of Calcium Ions That Are Released Upon Receipt of a Signal Relayed by the T Tubules From the Neuromuscular Junction. 
    45214   Sarcomere Organization  The Myofibril Assembly Process That Results in the Organization of Muscle Actomyosin Into Sarcomeres. the Sarcomere Is the Repeating Unit of a Myofibril in a Muscle Cell Composed of an Array of Overlapping Thick and Thin Filaments Between Two Adjacent Z Discs. 
    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. 
    5739   Mitochondrion  A Semiautonomous Self Replicating Organelle That Occurs in Varying Numbers Shapes and Sizes in the Cytoplasm of Virtually All Eukaryotic Cells. It Is Notably the Site of Tissue Respiration. 
    5759   Mitochondrial Matrix  The Gel Like Material with Considerable Fine Structure That Lies in the Matrix Space or Lumen of a Mitochondrion. It Contains the Enzymes of the Tricarboxylic Acid Cycle and in Some Organisms the Enzymes Concerned with Fatty Acid Oxidation. 
    16020   Membrane  Double Layer of Lipid Molecules That Encloses All Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins. 
    16529   Sarcoplasmic Reticulum  A Fine Reticular Network of Membrane Limited Elements That Pervades the Sarcoplasm of a Muscle Cell; Continuous Over Large Portions of the Cell and with the Nuclear Envelope; That Part of the Endoplasmic Reticulum Specialized For Calcium Release Uptake and Storage. 
    33017   Sarcoplasmic Reticulum Membrane  The Lipid Bilayer Surrounding the Sarcoplasmic Reticulum. 
    33018   Sarcoplasmic Reticulum Lumen  The Volume Enclosed by the Membranes of the Sarcoplasmic Reticulum. 
    5509   Calcium Ion Binding  Interacting Selectively and Non Covalently with Calcium Ions (ca2+). 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
