+ | [https://www.uniprot.org/uniprot/PSD10_HUMAN PSD10_HUMAN] Acts as a chaperone during the assembly of the 26S proteasome, specifically of the PA700/19S regulatory complex (RC). In the initial step of the base subcomplex assembly is part of an intermediate PSMD10:PSMC4:PSMC5:PAAF1 module which probably assembles with a PSMD5:PSMC2:PSMC1:PSMD2 module. Independently of the proteasome, regulates EGF-induced AKT activation through inhibition of the RHOA/ROCK/PTEN pahway, leading to prolonged AKT activation. Plays an important role in RAS-induced tumorigenesis.<ref>PMID:10613832</ref> <ref>PMID:11900540</ref> <ref>PMID:11779854</ref> <ref>PMID:16023600</ref> <ref>PMID:18040287</ref> <ref>PMID:19490896</ref> <ref>PMID:19729910</ref> <ref>PMID:20628200</ref> Acts as an proto-oncoprotein by being involved in negative regulation of tumor suppressors RB1 and p53/TP53. Overexpression is leading to phosphorylation of RB1 and proteasomal degradation of RB1. Regulates CDK4-mediated phosphorylation of RB1 by competing with CDKN2A for binding with CDK4. Facilitates binding of MDM2 to p53/TP53 and the mono- and polyubiquitination of p53/TP53 by MDM2 suggesting a function in targeting the TP53:MDM2 complex to the 26S proteasome. Involved in p53-independent apoptosis. Involved in regulation of NF-kappa-B by retaining it in the cytoplasm. Binds to the NF-kappa-B component RELA and accelerates its XPO1/CRM1-mediated nuclear export.<ref>PMID:10613832</ref> <ref>PMID:11900540</ref> <ref>PMID:11779854</ref> <ref>PMID:16023600</ref> <ref>PMID:18040287</ref> <ref>PMID:19490896</ref> <ref>PMID:19729910</ref> <ref>PMID:20628200</ref> | ||
