== Function ==
[https://www.uniprot.org/uniprot/PSMD4_ARATH PSMD4_ARATH] Plays a role in maintaining the structural integrity of the 19S regulatory particle (RP), subcomplex of the 26S proteasome. Plays a major role in both the direct and indirect recognition of ubiquitinated substrates of ubiquitin/26S proteasome-mediated proteolysis (UPP). Binds and presumably selects ubiquitin-conjugates for destruction. Prefers multiubiquitin chains rather than single ubiquitins, with a binding affinity for 'Lys-48'-linked ubiquitin chains. Acts as a potential docking subunit for both ubiquitin receptors RAD23s and DSK2s. Plays a role in the growth and development via the proteasome-dependent degradation of the ABA-signaling protein ABI5/DPBF1. Plays an important role for balancing cell expansion with cell proliferation rates during shoot development.<ref>PMID:12671091</ref> <ref>PMID:17971041</ref> <ref>PMID:19321709</ref> <ref>PMID:20059542</ref> <ref>PMID:21764993</ref> <ref>PMID:22751321</ref> <ref>PMID:8530351</ref> <ref>PMID:8570648</ref> <ref>PMID:9442033</ref> <ref>PMID:9741626</ref>
