The initiation of the mechanism of delivering proteins to the ER as protein synthesis occurs, commonly known as the signal hypothesis, involves a series of steps that occur in a specific order. In the left column, place numbers (1-8) adjacent to the phrases describing specific steps to indicate their proper order. Membrane threading of proteins involves specific types of proteins and RNA/protein complexes. In the right column use the following letter code to identify specific types of components: C for cytoplasmic proteins (made on cytoplasmic ribosomes); G is for G protein: I for integral membrane proteins; R for RNA protein complxes; and S for secreted proteins (proteins that have reached a soluble compartment by the signal hypothesis. Each phrase may have more than 1 component letter associated with it. Chronological Order Components SRP-dependent GTP hydrolysis Signal peptidase cleaves signal peptide Protein translocating channel opens Signal sequence binding Translation resumes SRP binds SRP receptor on membrane Newly synthesized protein is glycosylated Translational arrest (stoppage)what order do the events occur? what types of proteins are involved?
