The signal recognition particle (SRP) co-translationally targets proteins to the endoplasmic reticulum in eurkaryotes or to the plasma membrane in prokaryotes. As the initiating step, SRP binds to the ...
The crystal structure of the universal ribonucleoprotein core of the signal recognition particle suggests that the RNA moiety has been evolutionarily conserved because it plays an important role in ...
The signal recognition particle (SRP)-mediated translocation of proteins across the RER is a GTP dependent process. Analysis of the primary amino acid sequence of one protein subunit of SRP (SRP54), ...
A 4.5 kg/mol peptide released by an amoeban predator, Amoeba proteus, induced defensive behavioral changes in ciliates of the genus Euplotes. The interspecific signaling molecule named "A-factor" was ...
