Descrição geral
Product Source: Recombinant human UbcH5b Conjugating Enzyme expressed in E. coli.
The His6-tagged fusion protein of UbcH5b is charge and support ubiquitinylation in vitro. Unlike their GST-tagged counterparts, the His6-tagged UbcH5 family members all appear to form thiol ester conjugates with ubiquitin at a similar rate under similar conditions. The His-tagged version of this enzyme is not susceptible to self-ubiquitinylation. UbcH5b is highly homologous to the S. cerevisiae UbC4/5 family of E2 enzymes, demonstrated to be essential for degradation of regulatory and abnormal proteins. UbcH5b, together with UbcH5a and UbcH5c, are the most active class of E2 enzymes in cell extracts and are associated with regulation of a number of transcription factors including p53, NF-κB, and c-Fos.

Two very closely related human E2 ubiquitin conjugating enzymes, UbfH5B and UbcH5C, have been identified. These enzymes are products of distinct genes and are 88-89% identical in amino acid sequence to the recently described human E2, UbcH5 (now designated UbcH5A)

The last step in the activation of the transcription factor NF-kappaB is signal-induced, ubiquitin- and proteasome-mediated degradation of the inhibitor IkappaBalpha. Although most of the components involved in the activation and degradation pathways have been identified, the ubiquitin carrier proteins
