Target

  • Relevance

    Function: Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-6-linked may be involved in DNA repair; Lys-11-linked is involved in ERAD (endoplasmic reticulum-associated degradation) and in cell-cycle regulation; Lys-29-linked is involved in lysosomal degradation; Lys-33-linked is involved in kinase modification; Lys-48-linked is involved in protein degradation via the proteasome; Lys-63-linked is involved in endocytosis, DNA-damage responses as well as in signaling processes leading to activation of the transcription factor NF-kappa-B. Linear polymer chains formed via attachment by the initiator Met lead to cell signaling. Ubiquitin is usually conjugated to Lys residues of target proteins, however, in rare cases, conjugation to Cys or Ser residues has been observed. When polyubiquitin is free (unanchored-polyubiquitin), it also has distinct roles, such as in activation of protein kinases, and in signaling. Similarity: Belongs to the ubiquitin family. Contains 3 ubiquitin-like domains.

Answer

This is a relatively new antibody that has not yet been epitope mapped or tried in yeast. We are about to implement a trial 'try risk free' scheme which says that if an antibody is purchased and used in an experiment outside that written on the datasheet, and it is found not to work, in return for the negative data (which we can add to the datasheet to help other researchers) we will replace the antibody for one of equivalent value or refund it. We hope this will help It is therefore risk free for the researcher and it helps build information into our datasheets.

Answer

A single band at 32kD is detected in Western blotting. Although we do have pictures of Western blots, these are of very poor quality and therefore of little help.
