Abstract

This entry represents both the 9 kDa SRP9 and the 14 kDa SRP14 components. Both SRP9 and SRP14 have the same (beta)-alpha-beta(3)-alpha fold. The heterodimer has pseudo two-fold symmetry and is saddle-like, consisting of a curved six-stranded beta-sheet that has four helices packed on the convex side and an exposed concave surface lined with positively charged residues. The SRP9/SRP14 heterodimer is essential for SRP RNA binding, mediating the pausing of synthesis of ribosome associated nascent polypeptides that have been engaged by the targeting domain of SRP [PubMed7730321].
