  • Function

    E3 ubiquitin-protein ligase which targets misfolded chaperone substrates towards proteasomal degradation. Ubiquitinates NOS1 in concert with Hsp70 and Hsp40. Modulates the activity of several chaperone complexes, including Hsp70, Hsc70 and Hsp90. Mediates transfer of non-canonical short ubiquitin chains to HSPA8 that have no effect on HSPA8 degradation. Mediates polyubiquitination of DNA polymerase beta (POLB) at 'Lys-41', 'Lys-61' and 'Lys-81', thereby playing a role in base-excision repair: catalyzes polyubiquitination by amplifying the HUWE1/ARF-BP1-dependent monoubiquitination and leading to POLB-degradation by the proteasome. Mediates polyubiquitination of CYP3A4.
  • Tissue specificity

    Highly expressed in skeletal muscle, heart, pancreas, brain and placenta. Detected in kidney, liver and lung.
  • Pathway

    Protein modification; protein ubiquitination.
  • Sequence similarities

    Contains 3 TPR repeats.
    Contains 1 U-box domain.
  • Domain

    The TPR domain is essential for ubiquitination mediated by UBE2D1.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
    Auto-ubiquitinated; mediated by UBE2D1 and UBE2D2.
