    GO ID   Ontology GO Term Definition
    244   Spliceosomal Tri Snrnp Complex Assembly  The Formation of a Tri Snrnp Complex Containing U4 and U6 (or U4atac and U6atac) Snrnas and U5 Snrnas and Associated Proteins. This Includes Reannealing of U4 and U6 (or U4atac and U6atac) Snrnas Released From Previous Rounds of Splicing to Reform the U4/u6 Snrnp (or U4atac/u6atac Snrnp) As Well As the Subsequent Association of the U5 Snrnp with the U4/u6 Snrnp (or U4atac/u6atac Snrnp) to Form a Tri Snrnp That Is Ready to Reassemble Into Another Spliceosome Complex. 
    6397   MRNA Processing  Any Process Involved in the Conversion of a Primary MRNA Transcript Into One or More Mature Mrna(s) Prior to Translation Into Polypeptide. 
    8380   RNA Splicing  The Process of Removing Sections of the Primary RNA Transcript to Remove Sequences Not Present in the Mature Form of the RNA and Joining the Remaining Sections to Form the Mature Form of the Rna. 
    5634   Nucleus  A Membrane Bounded Organelle of Eukaryotic Cells in Which Chromosomes Are Housed and Replicated. in Most Cells the Nucleus Contains All of the Cell's Chromosomes Except the Organellar Chromosomes and Is the Site of RNA Synthesis and Processing. in Some Species or in Specialized Cell Types RNA Metabolism or DNA Replication May Be Absent. 
    5682   U5 Snrnp  A Ribonucleoprotein Complex That Contains Small Nuclear RNA U5. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    3674   Molecular_function  Elemental Activities Such As Catalysis or Binding Describing the Actions of a Gene Product At the Molecular Level. a Given Gene Product May Exhibit One or More Molecular Functions. 
    Chain B,E
    GO ID   Ontology GO Term Definition
    398   MRNA Splicing Via Spliceosome  The Joining Together of Exons From One or More Primary Transcripts of Messenger RNA (mrna) and the Excision of Intron Sequences Via a Spliceosomal Mechanism So That MRNA Consisting Only of the Joined Exons Is Produced. 
    5681   Spliceosomal Complex  Any of a Series of Ribonucleoprotein Complexes That Contain RNA and Small Nuclear Ribonucleoproteins (snrnps) and Are Formed Sequentially During the Splicing of a Messenger RNA Primary Transcript to Excise an Intron. 
    3676   Nucleic Acid Binding  Interacting Selectively and Non Covalently with Any Nucleic Acid. 
    3723   RNA Binding  Interacting Selectively and Non Covalently with an RNA Molecule or a Portion Thereof. 
    17070   U6 Snrna Binding  Interacting Selectively and Non Covalently with the U6 Small Nuclear RNA (u6 Snrna). 
    30623   U5 Snrna Binding  Interacting Selectively and Non Covalently with the U5 Small Nuclear RNA (u5 Snrna).
