Ubiquitin (Ub) is among the most phylogenetically conserved proteins known. The primary function of ubiquitin is to clear abnormal, foreign and improperly folded proteins by targeting them for degradation by the 26S proteosome. This small, 76 amino acid protein can be covalently attached to cellular proteins via an isopeptide linkage between the carboxy terminal group of ubiquitin and lysine amino groups on the acceptor protein. For proteolysis to occur, ubiquitin oligomers must be assembled. Ubiquitin chains on proteolytic substrates are commonly found to have an isopeptide bridge between Lysine 48 of one ubiquitin molecule and the carboxy-terminus of a neighboring ubiquitin molecule. Ubiquitin also plays a role in regulating signal transduction cascades through the elimination inhibitory proteins, such as IκBα and p27.
The Abbkine Ub (Acetyl Lys33) Rabbit Polyclonal Antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and synthesized peptide derived from the human Ub around the acetylation site of K33. The antibody has been validaed in WB, ELISA and reacts with Human, Mouse, Rat samples.
