Descrição geral
Produced from human cDNA, expressed in E. coli. Ubiquitin C-terminal hydrolases (UCHs) are a family of cysteine hydrolases that catalyze the hydrolysis of amides, esters and thioesters of the C-terminus of ubiquitin. Mammalian neuronal cells abundantly express a deubiquitylating enzyme, ubiquitin carboxy-terminal hydrolase 1 (UCH-L1). Mutations in UCH-L1 are linked to Parkinson′s disease as well as gracile axonal dystrophy (gad) in mice. In contrast to the universally expressed UCH-L3 isozyme, UCH-L1 is expressed exclusively in neurons and testis/ovary. It has been shown that UCH-L1 associates and co-localizes with monoubiquitin and elongates ubiquitin half-life and the suggestion is made that UCH-L1, with avidity and affinity for ubiquitin, ensures ubiquitin stability within neurons.

Armazenamento e estabilidade
As supplied, store at -80°C for up to 12 months from date of receipt. Avoid repeated freeze/thaw cycles. After initial defrost, aliquot (for extended storage it is recommended that aliquots be no smaller then 10 μL) and store at -80°C. Snap-freezing in a dry ice/ethanol bath or liquid nitrogen is recommended. As supplied, the enzyme is stable on ice for several hours.

Ubiquitin C-terminal hydrolases (UCH's) are a newly-defined class of thiol proteases implicated in the proteolytic processing of polymeric ubiquitin. They are important for the generation of monomeric ubiquitin, the active component of the eukaryotic ubiquitin-dependent proteolytic system. There are at

Database search using a bovine thymus ubiquitin C-terminal hydrolase sequence indicated 54% sequence identity with the abundant human neuron-specific protein gene product 9.5 (PGP9.5), which was then shown to possess the same activity [Wilkinson, Lee, Deshpande, Duerksen-Hughes, Boss & Pohl

The assumption that each enzyme expresses a single enzymatic activity in vivo is challenged by the linkage of the neuronal enzyme ubiquitin C-terminal hydrolase-L1 (UCH-L1) to Parkinson's disease (PD). UCH-L1, especially those variants linked to higher susceptibility to PD, causes
