Ubiquitin C-Terminal Hydrolase L1 in Tumorigenesis
Ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1, aka PGP9.5) is an abundant, neuronal deubiquitinating enzyme that has also been suggested to possess E3 ubiquitin-protein ligase activity and/or stabilize ubiquitin monomers in vivo. Recent evidence implicates dysregulation of UCH-L1 in the pathogenesis and progression of human cancers. Although typically only expressed in neurons, high levels o...
متن کاملIncreased Cerebrospinal Fluid Levels of Ubiquitin Carboxyl-Terminal Hydrolase L1 in Patients with Alzheimer's Disease
BACKGROUND Dysfunctions of the ubiquitin proteasome system (UPS), including the highly abundant neuronal enzyme ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1), and autophagy-related changes (lysosomal degradation) are implicated in several neurodegenerative disorders including Alzheimer's disease (AD). METHOD This study evaluated cerebrospinal fluid (CSF) levels of UCH-L1, protein deglycas...
متن کاملIntron-exon structure of ubiquitin c-terminal hydrolase-L1.
Parkinson's disease (PD) is a common neurodegenerative movement disorder characterized by tremor, bradykinesia, postural instability and muscular rigidity. Neuropathologically, it is defined by cell loss in the substantia nigra associated with the presence of intraneuronal inclusions called Lewy bodies (LB) and processes engorged with proteinaceous material, the Lewy neurites. The recent identi...
متن کاملRegulation of synaptic structure by ubiquitin C-terminal hydrolase L1.
Ubiquitin C-terminal hydrolase L1 (UCH-L1) is a deubiquitinating enzyme that is selectively and abundantly expressed in the brain, and its activity is required for normal synaptic function. Here, we show that UCH-L1 functions in maintaining normal synaptic structure in hippocampal neurons. We found that UCH-L1 activity is rapidly upregulated by NMDA receptor activation, which leads to an increa...
متن کاملUbiquitin C-terminal hydrolase L1 (UCH-L1): structure, distribution and roles in brain function and dysfunction
Ubiquitin C-terminal hydrolase L1 (UCH-L1) is an extremely abundant protein in the brain where, remarkably, it is estimated to make up 1-5% of total neuronal protein. Although it comprises only 223 amino acids it has one of the most complicated 3D knotted structures yet discovered. Beyond its expression in neurons UCH-L1 has only very limited expression in other healthy tissues but it is highly...
