CC -!- FUNCTION: Ubiquitin exists either covalently attached to another CC protein, or free (unanchored). When covalently bound, it is conjugated CC to target proteins via an isopeptide bond either as a monomer CC (monoubiquitin), a polymer linked via different Lys residues of the CC ubiquitin (polyubiquitin chains) or a linear polymer linked via the CC initiator Met of the ubiquitin (linear polyubiquitin chains). CC Polyubiquitin chains, when attached to a target protein, have different CC functions depending on the Lys residue of the ubiquitin that is linked: CC Lys-11-linked is involved in ERAD (endoplasmic reticulum-associated CC degradation) and in cell-cycle regulation; Lys-29-linked is involved in CC lysosomal degradation; Lys-33-linked is involved in kinase CC modification; Lys-48-linked is involved in protein degradation via the CC proteasome; Lys-63-linked is involved in endocytosis, and DNA-damage CC responses. Linear polymer chains formed via attachment by the initiator CC Met lead to cell signaling. Ubiquitin is usually conjugated to Lys CC residues of target proteins, however, in rare cases, conjugation to Cys CC or Ser residues has been observed. When polyubiquitin is free CC (unanchored-polyubiquitin), it also has distinct roles, such as in CC activation of protein kinases, and in signaling (By similarity). CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}. CC -!- MISCELLANEOUS: Ubiquitin is encoded by 16 different genes. Ubiquitin is CC generally synthesized as a polyubiquitin precursor with tandem head to CC tail repeats. Often, there is one to three additional amino acids after CC the last repeat, removed in the mature protein. Alternatively, CC ubiquitin extension protein is synthesized as a single copy of CC ubiquitin fused to a ribosomal protein (either eL40 or eS31) or to a CC ubiquitin-related protein (either RUB1 or RUB2). Following translation, CC extension protein is cleaved from ubiquitin. CC -!- MISCELLANEOUS: For the sake of clarity sequence features are annotated CC only for the first chain, and are not repeated for each of the CC following chains. CC -!- SIMILARITY: Belongs to the ubiquitin family. {ECO:0000305}.
