Human SRP RNA. The termini are towards the left.	|	pdb
		Approach of proteins SRP14, SRP9, and SRP19.	|	pdb
		SRP9 and SRP14 form a heterodimer. SRP19 binds to the tetraloop of helix 6.	|	pdb
		SRP9/14 bind the small domain. SRP19 binds also to helix 8.	|	pdb
		SRP9/14 makes additional contacts with RNA.	|	pdb
		SRP54 binds to helix 8. (Only the 54m-part is shown. A groove in SRP54m will bind the signal peptide.)	|	pdb
