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 lysosomal degradation;
CC Lys-33-linked is involved in kinase modification; Lys-48-linked is
CC involved in protein degradation via the proteasome; Lys-63-linked is
CC involved in endocytosis, and DNA-damage responses. Linear polymer
CC chains formed via attachment by the initiator Met lead to cell
CC signaling. Ubiquitin is usually conjugated to Lys residues of target
CC proteins, however, in rare cases, conjugation to Cys or Ser residues
CC 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: Ribosomal protein S27a is a component of the 40S subunit of
CC the ribosome.
CC -!- SUBUNIT: Ribosomal protein S27a is part of the 40S ribosomal subunit.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Ubiquitin]: Cytoplasm {ECO:0000250}. Nucleus
CC {ECO:0000250}.
CC -!- MISCELLANEOUS: Ubiquitin is encoded by several different genes. Ubi3
CC genes code for a single copy of ubiquitin fused to the ribosomal
CC proteins S27a. Ubi4 is synthesized as a polyubiquitin precursor with 5
CC exact head to tail repeats.
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 eS31 family. {ECO:0000305}.
