    basic FUNCTION
  • acting as a regulatory subunit of the 26s proteasome which is involved in the ATP-dependent degradation of ubiquitinated proteins
  • playing an important role in the development of hepatocellular carcinomas
  • ankyrin repeat anti-apoptotic oncoprotein that is commonly overexpressed in hepatocellular carcinomas and increases the degradation of TP53 and Rb (Chen 2008)
  • during ER stress, p28(GANK) enhances the unfolded protein response, promotes ER recovery from translational repression, and thereby facilitates cell's ability to cope with the stress conditions
  • is a key regulator of RAS-mediated activation of AKT1 through inhibition of the downstream RHOA/ROCK pathway and thus plays an essential role in RAS-induced tumorigenesis
  • chaperone of ubiquitin-proteasome, having an essential role in breast cancer metastasis
  • is crucial for breast cancer metastasis
  • is a regulator of cellular redox homeostasis, providing a link between oxidative stress and the development of hepatocellular carcinoma
  • may exert a pro-oncogenic function in the prostate

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • CDK4, PSMC4
  • directly binds to NF-kappaB/RELA and exports RELA from nucleus through a chromosomal region maintenance-1 (CRM1) dependent pathway, which results in the cytoplasmic retention of NF-kappaB/RELA (Chen 2008)
  • PSMD10 expression is regulated by a positive feedback loop involving CTNNB1, which may play a critical role in tumorigenesis and the progression of Hepatocellular carcinoma P
  • CDH1 was found to be involved in the PSMD10 induced invasion of breast cancer cells due to hypoxia
  • PSMD10 was physically associated with ATG7 in the cytoplasm, and this association was enhanced by initial nutrient deprivation
  • oncoprotein that facilitates the degradation of two key tumor suppressors, namely, RB1 and TP53
  • interact with the Kelch domain of KEAP1 and effectively competed with NFE2L2 for KEAP1 binding
  • involved in the inhibition of differentiation of hepatic stem cells (HSC) via triggering degradation of tumor suppressor proteins RB1, TP53, CEBPA and HNF4A
  • CELF1 is both a tumor suppressor and target of PSMD10-mediated degradation when unphosphorylated at Ser302
  • PSMD10-mediated reduction of CELF1 is critical for the development of hepatoblastoma (HBL)
  • PSMD10 is a novel downstream effector of KDM4A
