CC   -!- FUNCTION: Protein modifier that is covalently attached to lysine
CC       residues of substrate proteins, thereby targeting them for proteasomal
CC       degradation. The tagging system is termed pupylation.
CC       {ECO:0000255|HAMAP-Rule:MF_02106}.
CC   -!- PATHWAY: Protein degradation; proteasomal Pup-dependent pathway.
CC       {ECO:0000255|HAMAP-Rule:MF_02106}.
CC   -!- SUBUNIT: Strongly interacts with the proteasome-associated ATPase ARC
CC       through a hydrophobic interface; the interacting region of Pup lies in
CC       its C-terminal half. There is one Pup binding site per ARC hexamer
CC       ring. {ECO:0000255|HAMAP-Rule:MF_02106}.
CC   -!- DOMAIN: The N-terminal unstructured half of Pup provides a signal
CC       required to initiate unfolding and degradation by the proteasome but is
CC       not needed for pupylation, while the C-terminal helical half of Pup
CC       interacts with ARC to target proteins to the proteasome.
CC       {ECO:0000255|HAMAP-Rule:MF_02106}.
CC   -!- SIMILARITY: Belongs to the prokaryotic ubiquitin-like protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_02106}.
