The proteasome
How does it work? The proteasome consists of a cylindrical 20 S catalytic chamber (see Figure), capped on one or both ends by a 19 S regulatory complex. The regulatory complex (which is made of at least 18 different subunits, six of which are ATPases; not shown in the Figure) recognizes ubiquitinated proteins and is thought to drive their unfolding, although the mechanism is not understood. The...
متن کاملPrimes the Proteasome
P roteostasis, the precisely orchestrated balance between protein synthesis and degradation, plays a critical role in the maintenance of cell function. This is particularly the case for postmitotic cells such as cardiomyocytes and neurons, which rarely re-enter the cell cycle to divide and hence survive for decades. Disease-related stress can promote dysregu-lation of proteostasis, leading to a...
