Summary: Predicted to enable several functions, including MDM2/MDM4 family protein binding activity; endopeptidase activator activity; and p53 binding activity. Predicted to be involved in negative regulation of extrinsic apoptotic signaling pathway; regulation of G1/S transition of mitotic cell cycle; and regulation of proteasomal protein catabolic process. Predicted to be located in cytosol. Predicted to be part of proteasome activator complex. Predicted to be active in cytoplasm and nucleoplasm. Is expressed in genitourinary system and ventricular layer. Orthologous to human PSME3 (proteasome activator subunit 3). [provided by Alliance of Genome Resources, Dec 2024]

The results of the present study also indicated that all of the effects of the miR1955p inhibitor on ATDC5 cells were reversed by REGgamma silencing. The results also revealed that a miR1955p inhibitor inhibited the LPS induced repression of the Wnt/betacatenin signaling pathway and activation of nuclear factor (NF)kappaB signaling pathway in ATDC5 cells.

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.
