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-6-linked may be involved in DNA repair; Lys-11-linked is involved
CC in ERAD (endoplasmic reticulum-associated degradation) and in cell-
CC cycle regulation; Lys-29-linked is involved in proteotoxic stress
CC response and cell cycle; 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, DNA-damage
CC responses as well as in signaling processes leading to activation of
CC the transcription factor NF-kappa-B. Linear polymer chains formed via
CC attachment by the initiator Met lead to cell signaling. Ubiquitin is
CC usually conjugated to Lys residues of target proteins, however, in rare
CC cases, conjugation to Cys or Ser residues has been observed. When
CC polyubiquitin is free (unanchored-polyubiquitin), it also has distinct
CC roles, such as in activation of protein kinases, and in signaling.
CC {ECO:0000250|UniProtKB:P62987}.
CC -!- FUNCTION: [60S ribosomal protein L40]: Component of the 60S subunit of
CC the ribosome. Ribosomal protein L40 is essential for translation of a
CC subset of cellular transcripts, and especially for cap-dependent
CC translation of vesicular stomatitis virus mRNAs.
CC {ECO:0000250|UniProtKB:P62987}.
CC -!- SUBUNIT: Ribosomal protein L40 is part of the 60S ribosomal subunit.
CC Interacts with UBQLN1 (via UBA domain). {ECO:0000250|UniProtKB:P62987}.
CC -!- SUBCELLULAR LOCATION: [Ubiquitin]: Cytoplasm {ECO:0000250}. Nucleus
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [60S ribosomal protein L40]: Cytoplasm
CC {ECO:0000250}.
CC -!- PTM: [Ubiquitin]: Phosphorylated at Ser-65 by PINK1 during mitophagy.
CC Phosphorylated ubiquitin specifically binds and activates parkin
CC (PRKN), triggering mitophagy. Phosphorylation does not affect E1-
CC mediated E2 charging of ubiquitin but affects discharging of E2 enzymes
CC to form polyubiquitin chains. It also affects deubiquitination by
CC deubiquitinase enzymes such as USP30. {ECO:0000250|UniProtKB:P62987}.
CC -!- PTM: [Ubiquitin]: Mono-ADP-ribosylated at the C-terminus by PARP9, a
CC component of the PPAR9-DTX3L complex. ADP-ribosylation requires
CC processing by E1 and E2 enzymes and prevents ubiquitin conjugation to
CC substrates such as histones. {ECO:0000250|UniProtKB:P62987}.
CC -!- MISCELLANEOUS: Ubiquitin is encoded by 4 different genes. Uba52 and
CC Rps27a genes code for a single copy of ubiquitin fused to the ribosomal
CC proteins L40 and S27a, respectively. UBB and UBC genes code for a
CC polyubiquitin precursor with exact head to tail repeats, the number of
CC repeats differ between species and strains.
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}.
