General information
| Description | Stable HEK293 Cells-Rpn11-HTBH is a stably transfected derivative of the HEK293 (Human Embryonic Kidney 293) cell line, engineered to express a tagged version of Rpn11 (also known as PSMD14 or POH1), the deubiquitinase subunit of the 26S proteasome lid complex. Rpn11 is a Zn²⁺-dependent JAMM-domain deubiquitinase that removes ubiquitin chains from proteasome-bound substrates during proteasomal degradation. The HTBH tag (hexahistidine-TEV-biotin acceptor peptide-hexahistidine) enables affinity purification of Rpn11-containing complexes under native conditions, making this line particularly suited for proteasome complex purification and interactome studies. This cell line is applicable in studies of 26S proteasome biology, ubiquitin-proteasome pathway (UPS) regulation, Rpn11/PSMD14 function in protein quality control, proteasome assembly and dynamics, and proteasome inhibitor mechanism of action. It is also used for affinity purification of native proteasome complexes and as a model for studying deubiquitinase biology in the context of the proteasome. The HTBH tagging system enables highly stringent purification of biotinylated complexes using streptavidin-based pulldowns. Stable HEK293 Cells-Rpn11-HTBH are maintained as an adherent culture in DMEM supplemented with 10% FBS and the appropriate selection antibiotic to maintain transgene expression at 37°C in a humidified 5% CO₂ atmosphere. Cells are subcultured with Accutase at 80–90% confluency (split ratio 1:5 to 1:10). Medium renewed every 2–3 days. |
