WebThe cryo-EM structures of Nog2 particles are windows into nuclear stages of 60S subunit assembly. This review focuses primarily on principles that have emerged from studying the structures of Nog2-bound 60S subunit assembly intermediates. Nog2 is a GTPase AF present in the pre-60S subunit during nuclear stages of assembly. 22-24 This period of ... WebTM2 and Asp355 Function as Scaffolds in P2X5 Subunit Assembly—Our data are most compatible with the view that TM2 makes two essential contributions to hP2X 5 subunit oligomerization. First, the entire TM2 domain exerts a role that seems to have its basis in constraining the spatial mobility of the polypeptide chain, when the C-terminal end of the …
WebIonotropic receptors mediate rapid communication between neurons. These receptors are oligomers and are usually assembled from multiple subunit types. Receptors built from different subunit combinations have distinct functional properties, such as single-channel conductances, rates of desensitization and sensitivities to activators and inactivators; … Web5 Mar 2024 · If a subunit-specific assembly factor or a ribosomal protein is depleted, the biogenesis of the corresponding subunit is abrogated, whereas the biogenesis of the other continues; this leads to assembly of unequal numbers of the two subunits and distortion of the normal 1:1 production of the two ribosomal subunits.
WebThis chapter describes three methods for examining the inhibition of subunit formation in growing bacterial cells. The first method permits the determination of the IC 50 value for inhibition of assembly and protein synthesis. The second is a pulse and chase labeling procedure to measure the kinetics of subunit formation.
