    • Function
      Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro, in the presence or in the absence of BRCA1-BARD1 E3 ubiquitin-protein ligase complex, catalyzes the synthesis of 'Lys-48'-linked polyubiquitin chains. Does not transfer ubiquitin directly to but elongates monoubiquitinated substrate protein. Mediates the selective degradation of short-lived and abnormal proteins, such as the endoplasmic reticulum-associated degradation (ERAD) of misfolded lumenal proteins. Ubiquitinates huntingtin. May mediate foam cell formation by the suppression of apoptosis of lipid-bearing macrophages through ubiquitination and subsequence degradation of p53/TP53. Proposed to be involved in ubiquitination and proteolytic processing of NF-kappa-B; in vitro supports ubiquitination of NFKB1. In case of infection by cytomegaloviruses may be involved in the US11-dependent degradation of MHC class I heavy chains following their export from the ER to the cytosol. In case of viral infections may be involved in the HPV E7 protein-dependent degradation of RB1.
    • Tissue specificity
      Expressed in all tissues tested, including spleen, thymus, prostate, testis, ovary, small intestine, colon, peripheral blood leukocytes, T-lymphocytes, monocytes, granulocytes and bone marrow mononuclear cells. Highly expressed in brain, with highest levels found in cortex and striatum and at lower levels in cerebellum and brainstem.
    • Pathway
      Protein modification; protein ubiquitination.
    • Sequence similarities
      Belongs to the ubiquitin-conjugating enzyme family.
      Contains 1 UBA domain.
    • Post-translational
      Sumoylation at Lys-14 impairs catalytic activity.

    The antibody ab52930 is raised against a peptide located within the range of amino acids 140 - 170 of human HIP2/E2-25K, http://www.uniprot.org/uniprot/P61086. There are no known issues of detection of SUMOylated samples. I am not sure what is happening that would cause the signal to be fainter, unless there is some modification or degradation at or near the epitope that the antibody recognizes that only exists in the samples that are SUMOylated at Lys 14.
