WebAll cellular RNA and DNA is synthesized in the nucleus, but the attachment of amino acids to tRNAs for protein synthesis, catalysed by aminoacyl-tRNA synthetases, occurs in the cytosol. In cells in which protein synthesis is occurring at a rapid rate, the concentration of the transferase enzymes in the cytosol is very high and they can form a ... WebThere are three major destinations of proteins: (1) sent to other organelles, (2) released into the cytosol, and (3) secreted outside the cells. Secreting vesicles can also store the proteins until they receive a signal to release at a specific event. [In this figure] The journey of protein synthesis and transportation.

"WebOur findings suggest that stable S-nitrosylation reflects a protein conformation change that shields the nitrosothiol. To identify stable protein nitrosothiols, we developed a proteomic method for profiling S-nitrosylation. We examined the stability of over 100 S-nitrosylated proteins, and identified 10 stable nitrosothiols. " - Cytosol protein synthesis
