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}.
