UCHL3
Ubiquitin carboxyl-terminal hydrolase isozyme L3 is an enzyme that in humans is encoded by the ''UCHL3'' gene. Interactions UCHL3 has been shown to interact with NEDD8 and the tauopathy and synucleinopathy associated mutated ubiquitin molecule UBB+1. See also * Ubiquitin carboxy-terminal hydrolase L1 Ubiquitin carboxy-terminal hydrolase L1 (, ''ubiquitin C-terminal hydrolase'', ''UCH-L1'') is a deubiquitinating enzyme. Function UCH-L1 is a member of a gene family whose products hydrolyze small C-terminal adducts of ubiquitin to generate ...—an enzyme References Further reading * * * * * * * * * * * {{gene-13-stub ...

NEDD8
NEDD8 is a protein that in humans is encoded by the ''NEDD8'' gene. (in ''Saccharomyces cerevisiae'' this protein is known as Rub1) This ubiquitin-like protein, ubiquitin-like (UBL) protein becomes covalently conjugated to a limited number of cellular proteins, in a process called NEDDylation similar to ubiquitination. Human NEDD8 shares 60% amino acid sequence identity to ubiquitin. The primary known substrates of NEDD8 modification are the cullin subunits of cullin-based E3 ubiquitin ligases, which are active only when NEDDylated. Their NEDDylation is critical for the recruitment of E2 to the ligase complex, thus facilitating ubiquitin conjugation. NEDD8 modification has therefore been implicated in cell cycle progression and cytoskeletal regulation. Activation and conjugation As with ubiquitin and SUMO, NEDD8 is conjugated to cellular proteins after its C-terminal tail is processed. The NEDD8 activating E1 enzyme is a heterodimer composed of APPBP1 and UBA3 subunits. The APPBP1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...

Gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tauopathy
Tauopathies are a class of neurodegenerative diseases characterized by the aggregation of abnormal tau protein. Hyperphosphorylation of tau proteins causes them to dissociate from microtubules and form insoluble aggregates called neurofibrillary tangles. Various neuropathologic phenotypes have been described based on the anatomical regions and cell types involved as well as the unique tau isoforms making up these deposits. The designation 'primary tauopathy' is assigned to disorders where the predominant feature is the deposition of tau protein. Alternatively, diseases exhibiting tau pathologies attributed to different and varied underlying causes are termed 'secondary tauopathies'. Some neuropathologic phenotypes involving tau protein are Alzheimer's disease, frontotemporal dementia, progressive supranuclear palsy, and corticobasal degeneration. Tau protein Tau protein, also called tubulin associated unit or microtubule-associated protein tau (MAPT), is a microtubule-associate ...

Synucleinopathies
Synucleinopathies (also called α-Synucleinopathies) are neurodegenerative diseases characterised by the abnormal accumulation of aggregates of alpha-synuclein protein in neurons, nerve fibres or glial cells. There are three main types of synucleinopathy: Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA). Other rare disorders, such as various neuroaxonal dystrophies, also have α-synuclein pathologies. Additionally, autopsy studies have shown that around 6% of sporadic Alzheimer's Disease exhibit α-synuclein positive Lewy pathology, and are sub-classed as Alzheimer's Disease with Amygdalar Restricted Lewy Bodies (AD/ALB). Presentation The synucleinopathies have shared features of parkinsonism, impaired cognition, sleep disorders, and visual hallucinations. Synucleinopathies can sometimes overlap with tauopathies, possibly because of interaction between the synuclein and tau proteins. REM sleep behavior disorder (RBD) is a parasomnia ...
