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 -!- PTM: Is modified by deamidation of its C-terminal glutamine to
CC glutamate by the deamidase Dop, a prerequisite to the subsequent
CC pupylation process. {ECO:0000255|HAMAP-Rule:MF_02106}.
CC -!- SIMILARITY: Belongs to the prokaryotic ubiquitin-like protein family.
CC {ECO:0000255|HAMAP-Rule:MF_02106}.
