Puromycylation assay
WebPuromycylation assays reveal subcellular sites, such as nuclei, where puromycylated peptides accumulate post-release and which do not necessarily coincide with sites of active translation.

WebER stress and all three signaling branches of the UPR, including PERK. Furthermore, we revealed that PERK may play an important role in regulating the type I interferon response to PRRSV WebFor the puromycylation assay, wild-type and Ate1 −/− MEFs were treated with 10 µg/mL puromycin for 15 min at 37 °C. Cells were collected and lysed by sonication to measure the total protein concentration using the Pierce BCA Protein Assay Kit. Here, 16 µg total protein/lane of each sample was loaded for SDS-PAGE electrophoresis.
WebPuromycin is a tyrosyl-tRNA mimic that blocks translation by labeling and releasing elongating polypeptide chains from translating ribosomes. Puromycin has been used in molecular biology research for decades as a translation inhibitor. The Webwe combined puromycylation with a proximity ligation assay (puro-PLA) (Figure 4D) (tom Dieck et al., 2015). Axons that were not treated with PDL-coated beads showed very few SNAP25 puro-PLA puncta, while treatment with PDL-coated beads induced the local synthesis of SNAP25 (Figure 4E). As before, we tested how persistent the induction of …
WebNational Center for Biotechnology Information WebAug 3, 2024 · Therefore, we decided to measure general protein synthesis, a proxy for pAbp function, using the puromycylation assay. Puromycylation takes advantage of puromycin, an amino-nucleoside antibiotic. Puromycin resembles a charged-tRNA and causes termination of mRNA translation by incorporating itself into a growing polypeptide chain from …
