This is a synthetic peptide designed for use in combination with anti-UBXN1 Antibody. It may block above mentioned antibody from binding to its target protein in western blot and/or immunohistochecmistry under proper experimental settings. There is no guarantee for its use in other applications.
UBXN1 is a ubiquitin-binding protein that interacts with the BRCA1- BARD1 heterodimer, and regulates its activity. It specifically binds 'Lys-6'-linked polyubiquitin chains. Interaction with autoubiquitinated BRCA1,it leads to inhibit the E3 ubiquitin-protein ligase activity of the BRCA1-BARD1 heterodimer. It is a component of a complex required to couple deglycosylation and proteasome-mediated degradation of misfolded proteins in the endoplasmic reticulum that are retrotranslocated in the cytosol.
