Summary: Predicted to enable endopeptidase activator activity; peptidase activity; and proteasome binding activity. Predicted to be involved in several processes, including double-strand break repair; protein K63-linked deubiquitination; and regulation of proteasomal protein catabolic process. Part of proteasome accessory complex. Is expressed in central nervous system and genitourinary system. Orthologous to human PSMD14 (proteasome 26S subunit, non-ATPase 14).

An Arsenite Relay between PSMD14 and AIRAP Enables Revival of Proteasomal DUB Activity.
Title: An Arsenite Relay between PSMD14 and AIRAP Enables Revival of Proteasomal DUB Activity.
T cell-specific deletion of the gene encoding the deubiquitinase POH1 compromised the development of mature T cells, especially CD4(+)Foxp3(+) Treg cells. Moreover, POH1 deficiency significantly attenuated the transition of CD25(+) Treg cell precursors into Foxp3(+) Treg cells accompanied by downregulation of interleukin 2 (IL-2)-STAT5 signaling.

Study thereby reveals that POH1-mediated deubiquitination of pro-IL-1beta is an important regulatory event that restrains inflammatory responses for the maintenance of immune homeostasis.
Title: POH1 deubiquitinates pro-interleukin-1β and restricts inflammasome activity.
Conditional knockout of Poh1 alleles results in reduced E2F1 expression in primary mouse liver cells.

These results identify a novel mechanism of Mitf regulation in osteoclasts by POH1.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
