    text
  • maintained on the cytoplasmic side of the ER by indirect interaction with the ER membrane or with another protein
  • targeted to a cytoplasmic compartment as a soluble form
    • basic FUNCTION
  • involved in the maturation of the 20S proteasomes
  • is a proteaseome assembly chaperone that dimerizes with PSMG2, to form the PSMG1/PSMG2 complex
  • PSMG1 and PSMG4 might be involved in various cancers, including acute myeloid leukemia (AML)
