Human/Mouse/Rat PDHX Antibody

UCH-L3 (Ubiquitin carboxyterminal hydrolase isozyme 3) is a 26‑28 kDa member of the peptidase C12 family of enzymes. It shows wide expression, being noted in adipocytes, renal duct epithelium, neurons, and striated muscle. UCH-L3 cleaves both monomeric ubiquitin (Ub) from Ub-protein conjugates, and a GGLRQ peptide from the C-terminus of the Ub-like protein NEDD-8. Notably, UCH-L3 activity is muted in the presence of Ub interacting dimers. Human UCH-L3 is 230 amino acids (aa) in length. It is phosphorylated on Ser75 and Ser130, and contains two ubiquitin-binding sequences between aa 40‑57 and 178‑186. Four potential splice forms have been reported. Two show a four aa deletion between aa 15‑18, with one also containing a 14 aa substitution for aa 179 - 230. Two others contain an alternative start site at Met37, one of which is also accompanied by a seven aa substitution for aa 143‑230. Full-length human UCH-L3 shares 98% aa identity with mouse and rat UCH-L3.
