    GO ID   Ontology GO Term Definition
    6614   Srp Dependent Cotranslational Protein Targeting to Membrane  The Targeting of Proteins to a Membrane That Occurs During Translation and Is Dependent Upon Two Key Components the Signal Recognition Particle (srp) and the Srp Receptor. Srp Is a Cytosolic Particle That Transiently Binds to the Endoplasmic Reticulum (er) Signal Sequence in a Nascent Protein to the Large Ribosomal Unit and to the Srp Receptor in the Er Membrane. 
    48500   Signal Recognition Particle  A Complex of Protein and RNA Which Facilitates Translocation of Proteins Across Membranes. 
    3924   Gtpase Activity  Catalysis of the Reaction: GTP + H2o = GDP + Phosphate.
