UCH-L1/PGP9.5 Antibody (31A3)

UchL1 (ubiquitin C-terminal hydrolase), also known as PGP9.5 (protein gene product 9.5) and PARK5, is a neuronal biomarker and ubquitin system protein (reviewed in Day and Thompson, 2010). UchL1 is a highly conserved antibody and has shown that it is expressed in neurons and neuroendocrine cells in vertebrates where it comprises about 5-10% of soluble cytoplasmic proteins. A minor proportion of UchL1 in brain is tightly bound to the membrane. UchL1 antibody is also expressed in human oocytes and spermatogonia. It is important to note that the use of an antibody as a biomarker in this case does not imply that an antibody defines absolute tissue specificity. Rather, it means that PGP9.5 is expressed in neurons and neuroendrocine cells at significantly higher levels than in other cell types.
Functionally, UchL1 antibody is a thiol protease enzyme that recognizes and hydrolyzes a peptide bond at the C-terminal glycine of ubiquitin. UchL1 antibody also binds to free monoubiquitin and inhibits monoubiquitin degradation in lysosomes; it may function to stabilize monoubiquitin within neurons. A mutation in the UchL1 gene has been found to cause a form of Parkinson's disease, and this discovery has spurred considerable research interest in UchL1 and to its alternative name of PARK5.
Antibody to UchL1 is widely used as an immunohistochemical marker of nerves and neuroendocrine cells. The UchL1 clone 31A3 antibody stains neuronal cell bodies and axons in the central and peripheral nervous systems as well as small nerve fibers in peripheral tissues, including epidermal tissues (Day & Thompson, 2010). The antibody also stains neuroendrocrine cells in the kidney, pituitary, thyroid, pancreas, gastrointestinal tract, and tumors of the diffuse neuroendocrine system. This antibody has also identified UchL1 expression in renal tubule spermatogonia, testis, ovary, and both pregnant and non-pregnant corpus luteum. In western blots, the antibody identifies UchL1 as a band of approximately 20-30 kDa. The antibody is specific to UchL1 and does not cross-react with the closely related UchL3 protein (Yi et al, 2007).
