Immune-mediated Necrotizing Myopathy With Increased Creatine Phosphokinase and Positive Signal Recognition Particle: A Case Report
Background: Knowledge about Immune-Mediated Necrotizing Myopathy (IMNM) has received significantly attention in recent years. In this study, we report a rare case of IMNM with increased Creatine Phosphokinase (CPK) and positive Signal Recognition Particle (SRP). Clinical Presentation and Intervention: The case was a 67-year-old male patient referred to Firozgar hospital affiliated to the Iran ...
متن کاملThe signal recognition particle.
The signal recognition particle (SRP) and its membrane-associated receptor (SR) catalyze targeting of nascent secretory and membrane proteins to the protein translocation apparatus of the cell. Components of the SRP pathway and salient features of the molecular mechanism of SRP-dependent protein targeting are conserved in all three kingdoms of life. Recent advances in the structure determinatio...
متن کاملGTP hydrolysis by complexes of the signal recognition particle and the signal recognition particle receptor
Translocation of proteins across the endoplasmic reticulum membrane is a GTP-dependent process. The signal recognition particle (SRP) and the SRP receptor both contain subunits with GTP binding domains. One GTP-dependent reaction during protein translocation is the SRP receptor-mediated dissociation of SRP from the signal sequence of a nascent polypeptide. Here, we have assayed the SRP and the ...
متن کاملInteraction of signal-recognition particle 54 GTPase domain and signal-recognition particle RNA in the free signal-recognition particle.
The signal-recognition particle (SRP) is a ubiquitous protein-RNA complex that targets proteins to cellular membranes for insertion or secretion. A key player in SRP-mediated protein targeting is the evolutionarily conserved core consisting of the SRP RNA and the multidomain protein SRP54. Communication between the SRP54 domains is critical for SRP function, where signal sequence binding at the...
متن کاملSRPDB (Signal Recognition Particle Database)
The Signal Recognition Particle Database (SRPDB) at http://psyche.uthct.edu/dbs/SRPDB/SRPDB.html and http://bio.lundberg.gu.se/dbs/SRPDB/SRPDB.html assists in the better understanding of the structure and function of the signal recognition particle (SRP), a ribonucleoprotein complex that recognizes signal sequences as they emerge from the ribosome. SRPDB provides alphabetically and phylogenetic...
