ubiquitin
u·biq·ui·tin U5001600 (yo͞o-bĭk′wĭ-tĭn)n. A small protein found in all eukaryotic cells that attaches to other proteins, thereby regulating their activity or location or marking them for degradation.
[ubiquit(ous) + -in.]ubiquitin (juːˈbɪkwɪtɪn) n (Biochemistry) biochem a small polypeptide, found in most eukaryotic cells, that combines with other proteins to make them susceptible to degradation[C20: from ubiquitous + -in] uˌbiquitiˈnation nubiquitin
ubiquitin[yü′bik·wə‚tin] (biochemistry) A small, 76-amino-acid, highly conserved protein present in the cytoplasm and nucleus of all eukaryotes (but not eubacteria and archaea). The covalent, ATP-dependent linkage of multiple ubiquitin molecules to proteins serves as a signal for their degradation by the 26S proteasome. ubiquitin
u·biq·ui·tin (ū-bik'kwi-tin), [MIM*191320] A small (76 amino acyl residues) protein found in all cells of higher organisms and one with a structure that has changed minimally during evolutionary history; involved in at least two processes; histone modification and intracellular protein breakdown.ubiquitin (yo͞o-bĭk′wĭ-tĭn)n.

Ubiquitin is linked by covalent bonds to proteins destined for destruction by PROTEASOMES.ubiquitin a small PROTEIN, present in all eukaryotic cells (ubiquitous protein), containing a highly conserved sequence of 76 AMINO ACIDS, that is identical in a wide range of organisms including humans, fish and insects. Ubiquitin is involved in a number of cellular functions, such as protein degradation and modifications to CHROMATIN structure.See UB
