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 -!- FUNCTION: [60S ribosomal protein L40]: Component of the 60S subunit of CC the ribosome. {ECO:0000250}. CC -!- SUBUNIT: Ribosomal protein L40 is part of the 60S ribosomal subunit. CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: [Ubiquitin]: Cytoplasm {ECO:0000250}. Nucleus CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: [60S ribosomal protein L40]: Cytoplasm CC {ECO:0000250}. CC -!- SIMILARITY: In the N-terminal section; belongs to the ubiquitin family. CC {ECO:0000305}. CC -!- SIMILARITY: In the C-terminal section; belongs to the eukaryotic CC ribosomal protein eL40 family. {ECO:0000305}.
