J Biol Chem 2003; 278 : 28490–28500. Ubiquitin is a small (8.6 kDa) regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously. It was discovered in 1975 by Gideon Goldstein and further characterized throughout the late 1970s and 1980s. Four genes in the human genome code for ubiquitin: UBB, UBC, UBA52 and … See more Ubiquitin (originally, ubiquitous immunopoietic polypeptide) was first identified in 1975 as an 8.6 kDa protein expressed in all eukaryotic cells. The basic functions of ubiquitin and the components of the ubiquitylation … See more Ubiquitin is encoded in mammals by 4 different genes. UBA52 and RPS27A genes code for a single copy of ubiquitin fused to the ribosomal proteins L40 and S27a, respectively. The See more The ubiquitination system functions in a wide variety of cellular processes, including: • Antigen processing • Apoptosis • Biogenesis of organelles See more Pathogenesis The ubiquitin pathway has been implicated in the pathogenesis of a wide range of diseases and disorders including: • See more Ubiquitin is a small protein that exists in all eukaryotic cells.
