CC -!- FUNCTION: Plays a role in maintaining the structural integrity of the
CC 19S regulatory particle (RP), subcomplex of the 26S proteasome. Plays a
CC major role in both the direct and indirect recognition of ubiquitinated
CC substrates of ubiquitin/26S proteasome-mediated proteolysis (UPP).
CC Binds and presumably selects ubiquitin-conjugates for destruction.
CC Prefers multiubiquitin chains rather than single ubiquitins, with a
CC binding affinity for 'Lys-48'-linked ubiquitin chains. Acts as a
CC potential docking subunit for both ubiquitin receptors RAD23s and
CC DSK2s. Plays a role in the growth and development via the proteasome-
CC dependent degradation of the ABA-signaling protein ABI5/DPBF1. Plays an
CC important role for balancing cell expansion with cell proliferation
CC rates during shoot development. {ECO:0000269|PubMed:12671091,

CC ECO:0000269|PubMed:9741626}.
CC -!- SUBUNIT: Component of the 19S regulatory particle (RP/PA700) base
CC subcomplex of the 26S proteasome. The 26S proteasome is composed of a
CC core protease (CP), known as the 20S proteasome, capped at one or both
CC ends by the 19S regulatory particle (RP/PA700). The RP/PA700 complex is
CC composed of at least 17 different subunits in two subcomplexes, the
CC base and the lid, which form the portions proximal and distal to the
CC 20S proteolytic core, respectively. Interacts with PI4KG4. Interacts
CC with RAD23s and DSK2s via its UIM3 and UIM1 motif, respectively.
CC Interacts with 'Lys-48'-linked polyubiquitin chains via its UIM1 motif.

CC -!- TISSUE SPECIFICITY: Ubiquitous with highest expression in flowers.
CC {ECO:0000269|PubMed:14623884}.
CC -!- PTM: Phosphorylated by PI4KG4 in vitro. {ECO:0000269|PubMed:17880284}.
CC -!- DISRUPTION PHENOTYPE: Displays reduced seed germination, growth rate,
CC stamen number, genetic transmission through the male gamete, hormone-
CC induced cell division and increased oxidative stress tolerance. Is also
CC more sensitive to abscisic acid (ABA), salt, sucrose stress, heat shock
CC and DNA-damaging agents and shows a decreased sensitivity to cytokinin
CC and auxin. In flowers, epidermal cells in petals were larger than those
CC in the wild type. {ECO:0000269|PubMed:12671091,

CC -!- SIMILARITY: Belongs to the proteasome subunit S5A family.
