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-48-linked is involved in protein degradation via the proteasome.
CC Linear polymer chains formed via attachment by the initiator Met lead
CC to cell signaling. Ubiquitin is usually conjugated to Lys residues of
CC target proteins, however, in rare cases, conjugation to Cys or Ser
CC residues has been observed. When polyubiquitin is free (unanchored-
CC polyubiquitin), it also has distinct roles, such as in activation of
CC protein kinases, and in signaling (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- MISCELLANEOUS: Ubiquitin is synthesized as a polyubiquitin precursor
CC with exact head to tail repeats. Some ubiquitin genes contain a single
CC copy of ubiquitin fused to a ribosomal protein. In D.discoideum there
CC are 9 genes: ubqA: 5 copies of Ub and a final Asn; ubqB: 1 copy of Ub
CC and ribosomal protein L40; ubqC: 1 copy of Ub and ribosomal protein
CC S27A; ubqD: 3 copies of Ub and a final Leu; ubqF: 7 copies of Ub and a
CC final Asn; ubqG: 5 copies of Ub and a final Leu; ubqH: 5 copies of Ub
CC and a final Asn; ubqI: 4 copies of Ub and a final Asn; ubqJ: 4 copies
CC of Ub and a final Asn.
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}.
