TLDR
Mutations in the newly identified gene appear to be responsible for the pathogenesis of Autosomal recessive juvenile parkinsonism, and the protein product is named ‘Parkin’.Abstract:
Parkinson's disease is a common neurodegenerative disease with complex clinical features1. Autosomal recessive juvenile parkinsonism (AR-JP)2,3 maps to the long arm of chromosome 6 (6q25.2-q27) and is linked strongly to the markers D6S305 and D6S253 (ref. 4); the former is deleted in one Japanese AR-JP patient5. By positional cloning within this microdeletion, we have now isolated a complementary DNA clone of 2,960 base pairs with a 1,395-base-pair open reading frame, encoding a protein of 465 amino acids with moderate similarity to ubiquitin at the amino terminus and a RING-finger motif at the carboxy terminus. The gene spans more than 500 kilobases and has 12 exons, five of which (exons 3–7) are deleted in the patient. Four other AR-JP patients from three unrelated families have a deletion affecting exon 4 alone. A 4.5-kilobase transcript that is expressed in many human tissues but is abundant in the brain, including the substantia nigra, is shorter in brain tissue from one of the groups of exon-4-deleted patients. Mutations in the newly identified gene appear to be responsible for the pathogenesis of AR-JP, and we have therefore named the protein product ‘Parkin’.read more

PINK1/Parkin-mediated mitophagy in mammalian cells.
Akinori Eiyama,Koji Okamoto +1 more
TL;DR: This review highlights recent breakthroughs addressing the key issues of how PINK1 activates Parkin in response to mitochondrial malfunction, how Parkin localizes specifically to impaired mitochondria, and how ubiquitination and deubiquitination regulate Pink1/Parkin-mediated mitophagy.

TL;DR: In this paper, the authors discuss the latest findings regarding the impact of mitochondrial dynamics and mitophagy on the development and progression of cardiovascular pathologies, including diabetic cardiomyopathy, atherosclerosis, damage from ischaemia-reperfusion, cardiac hypertrophy and decompensated heart failure.

Mitochondrial dysfunction and oxidative stress in Parkinson's disease and monogenic parkinsonism
TL;DR: Evidence from both sporadic and genetic forms of Parkinson's disease that implicate both mitochondria and oxidative stress as central players in disease pathogenesis are reviewed.

Parkinsonian Mimetics Induce Aspects of Unfolded Protein Response in Death of Dopaminergic Neurons
TL;DR: The involvement of UPR in these widely used neurotoxin models supports the role of ubiquitin-proteasome pathway dysfunction in PD.
Journal ArticleDOI
The role of pathogenic DJ-1 mutations in Parkinson's disease
TL;DR: No mutations were found in the cohort of later onset sporadic pathologically confirmed cases, suggesting that DJ‐1 mutations may only rarely contribute to the cause of this more typical sporadic form of the disease.

TL;DR: A mutation was identified in the α-synuclein gene, which codes for a presynaptic protein thought to be involved in neuronal plasticity, in the Italian kindred and in three unrelated families of Greek origin with autosomal dominant inheritance for the PD phenotype.

Alpha-synuclein in Lewy bodies.

TL;DR: Strong staining of Lewy bodies from idiopathic Parkinson's disease with antibodies for α-synuclein, a presynaptic protein of unknown function which is mutated in some familial cases of the disease, indicates that the LewY bodies from these two diseases may have identical compositions.

Mitochondrial complex I deficiency in Parkinson's disease.
TL;DR: Results indicated a specific defect of Complex I activity in the substantia nigra of patients with Parkinson's disease, which adds further support to the proposition that Parkinson’s disease may be due to an environmental toxin with action(s) similar to those of MPTP.
Journal ArticleDOI
The ubiquitin-proteasome proteolytic pathway
TL;DR: Two studies clearly demonstrate that the ubiquitin-proteasome system is involved not only in complete destruction of its protein substrates, but also in limited proteolysis and posttranslational processing in which biologically active peptides or fragments are generated.
