General annotation (Comments)

Function	Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-11-linked is involved in ERAD (endoplasmic reticulum-associated degradation) and in cell-cycle regulation; Lys-29-linked is involved in lysosomal degradation; Lys-33-linked is involved in kinase modification; Lys-48-linked is involved in protein degradation via the proteasome; Lys-63-linked is involved in endocytosis, and DNA-damage responses. Linear polymer chains formed via attachment by the initiator Met lead to cell signaling. Ubiquitin is usually conjugated to Lys residues of target proteins, however, in rare cases, conjugation to Cys or Ser residues has been observed. When polyubiquitin is free (unanchored-polyubiquitin), it also has distinct roles, such as in activation of protein kinases, and in signaling By similarity.
Subcellular location	Cytoplasm By similarity. Nucleus By similarity.
Miscellaneous	Ubiquitin is encoded by 16 different genes. Ubiquitin is generally synthesized as a polyubiquitin precursor with tandem head to tail repeats. Often, there is one to three additional amino-acids after the last repeat, removed in the mature protein. Alternatively, ubiquitin extension protein is synthesized as a single copy of ubiquitin fused to a ribosomal protein (either L40 or S27A) or to an ubiquitin-related protein (either RUB1 or RUB2). Following translation, extension protein is cleaved from ubiquitin. For the sake of clarity sequence features are annotated only for the first chain, and are not repeated for each of the following chains.
Sequence similarities	Belongs to the ubiquitin family. Contains 4 ubiquitin-like domains.
