  • Function

    Acts as a regulatory subunit of the 26 proteasome which is involved in the ATP-dependent degradation of ubiquitinated proteins.
    Binds to the intracellular domain of tumor necrosis factor type 1 receptor. The binding domain of TRAP1 and TRAP2 resides outside the death domain of TNFR1.
  • Tissue specificity

    Found in skeletal muscle, liver, heart, brain, kidney, pancreas, lung and placenta.
  • Sequence similarities

    Belongs to the proteasome subunit S2 family.
    Contains 7 PC repeats.
