Ubiquitin is a small, highly conserved protein found in all eukaryotic cells. Through its covalent attachment to other proteins, ubiquitin regulates numerous important cellular processes including apoptosis, transcription, and the progression of the cell cycle. Ubiquitin expression is unusual: it is encoded and expressed as multimeric head-to-tail repeats (polyubiquitins) that are post-translationally cleaved into monomers, or fused with ribosomal proteins L40 and S27a. The ubiquitin moiety is… CONTINUE READING
