Webb27 jan. 2024 · Rpn4 serves as the master regulator of proteasome levels in baker's yeast and is tightly controlled by the proteasome; if the proteasome system is overstrained, Rpn4 accumulates and induces a 2–4 times upregulation of components of the ubiquitin–proteasome system compared with nonstressed conditions (Xie & Varshavsky, … A thioether-macrocyclic peptide library was constructed by using ClAc-F as an initiator in a genetically reprogrammed in vitro translation system42. The two genetic codes NNW and NNU were designed. The NNW code contained all 20 natural amino acids. The NNU code contained four N-methyl amino acids: N … Visa mer Antibodies to the indicated proteins were purchased from the following vendors: BRD4 (ab128874), BRD2 (ab139690), PSMD14 (ab109123) … Visa mer Recombinant PSMD2 was purified from BL21 gold (DE3) cells (Invitrogen) transformed with a pET 52b plasmid containing full-length … Visa mer Affinity selection of peptidic macrocycles binding to PSMD2 was conducted using Avi-tagged PSMD2 purified as described above. Briefly, 10 µM mRNA library was hybridized with a … Visa mer Phage display using N-terminally expressed peptide libraries was conducted as previously published41.
