Signal recognition particle binds to translating ribosomes before emergence of a signal anchor sequence. [PDF]
The bacterial signal recognition particle (SRP) is part of the machinery that targets ribosomes synthesizing membrane proteins to membrane-embedded translocons co-translationally. Recognition of nascent membrane proteins occurs by virtue of a hydrophobic

Sequential Checkpoints Govern Substrate Selection During Cotranslational Protein Targeting [PDF]
Proper protein localization is essential for all cells. However, the precise mechanism by which high fidelity is achieved is not well understood for any protein-targeting pathway.

X-ray structures of the signal recognition particle receptor reveal targeting cycle intermediates. [PDF]
The signal recognition particle (SRP) and its conjugate receptor (SR) mediate cotranslational targeting of a subclass of proteins destined for secretion to the endoplasmic reticulum membrane in eukaryotes or to the plasma membrane in prokaryotes ...

The Signal Recognition Particle Database (SRPDB) [PDF]
The signal recognition particle database (SRPDB) is located at the University of Texas Health Science Center at Tyler and includes tabulations of SRP RNA, SRP protein and SRP receptor sequences. The sequences are annotated with links to the primary databases. They are ordered alphabetically or phylogenetically and are available in aligned form.

Signal recognition particle prevents N-terminal processing of bacterial membrane proteins
Bacterial proteins are synthesized with formyl-methionine in their N-terminus, but most of them are co-translationally deformylated. Here, the authors show that inner-membrane proteins are protected from deformylation by the binding of the signal ...

Real-time observation of signal recognition particle binding to actively translating ribosomes
The signal recognition particle (SRP) directs translating ribosome-nascent chain complexes (RNCs) that display a signal sequence to protein translocation channels in target membranes.

Signal Sequence Processing in Rough Microsomes [PDF]
Secretory proteins are synthesized with a signal sequence that is usually cleaved from the nascent protein during the translocation of the polypeptide chain into the lumen of the endoplasmic reticulum.

A Distinct Mechanism to Achieve Efficient Signal Recognition Particle (SRP)-SRP Receptor Interaction by the Chloroplast SRP Pathway [PDF]
Cotranslational protein targeting by the signal recognition particle (SRP) requires the SRP RNA, which accelerates the interaction between the SRP and SRP receptor 200-fold.
