General description
Ubiquitin functions as a marker to indicate the fate of other proteins in the cell. It can be attached as a single molecule or as a polyubiquitin chain. Although ubiquitinated proteins are oftentimes tagged for degradation by the 20S proteosome, ubiquitination can also indicate alternative fates depending on the lysine residue that is involved in linking the ubiquitin chain to the target protein.Ubiquitin chains linked by Lys33 to kinase substrates such as AMP-activated protein kinases, (AMPKα1, BRSK1, MARK3, MARK4, and NUAK1), may activate or deactivate these proteins, supporting the role for uniquitin in regulating signaling.
Specificity
Broad species reactivity expected based on sequence similarity.
This antibody recognizes Ubiquitin at the N-terminus
Immunogen
Epitope: N-terminus

This Anti-Ubiquitin antibody is validated for use in IP & WB for the detection of the Ubiquitin protein.
Western Blot Analysis: 0.5 µg/mL from a representative lot detected Ubiquitin on 10 µg of HeLa cell lysate.
Quality
Evaluated by Immunoprecipitation in serum starved HeLa cell lysate.
Immunoprecipitation Analysis: 10 µg of this antibody detected Ubiquitin on 5 µL of serum starved HeLa cell lysate.
Immunoprecipitation Analysis: 10 µg of this antibody detected Ubiquitin on 5 µL of serum starved HeLa cell lysate.

The final outcome of protein polyubiquitylation is often proteasome-mediated proteolysis, meaning that "proofreading" of ubiquitylation by ubiquitin proteases (UBPs) is crucial. Transcriptional arrest can trigger ubiquitin-mediated proteolysis of RNA polymerase II (RNAPII) so a UBP reversing RNAPII ubiquitylation might be
