S-domain assembly of the signal recognition particle

A Elisabeth Sauer-Eriksson et al. Curr Opin Struct Biol. 2003 Feb.

Abstract

The signal recognition particle (SRP) is a phylogenetically conserved ribonucleoprotein that associates with ribosomes to mediate the targeting of membrane and secretory proteins to biological membranes. In higher eukaryotes, SRP biogenesis involves the sequential binding of SRP19 and SRP54 proteins to the S domain of 7S RNA. The recently determined crystal structures of SRP19 in complex with the S domain, and that of the ternary complex of SRP19, the S domain and the M domain of SRP54, provide insight into the molecular basis of S-domain assembly and SRP function.
