 Rpt, Regulatory particle triple-A (Rpt) subunits of 26S proteasomes;  triple-A (or AAA) is a family of proteins within the AAA+ superfamily of ATPases associated with various cellular activities

Historical Background

Regulatory particle triple-A (Rpt) subunits are associated with the ubiquitin-proteasome system, a central mechanism of protein breakdown with a rich historical background. Aaron Ciechanover, Avram Hershko, and Irwin Rose were awarded the 2004 Nobel Prize in Chemistry for their “discovery of ubiquitin-mediated protein degradation” by proteasomes and have outlined some of this history in reviews (e.g., Ciechanover 2010). The term “proteasome” was first coined by Arrigo et al. (1988) for a “large alkaline multifunctional protease” known to mediate energy-dependent intracellular protein breakdown, once it was clear that this protease was related to the ring-shaped “prosomes” of unknown function commonly found in eukaryotic cells. The Rpt nomenclature was later...
