Summaries for SNCA Gene

Entrez Gene Summary for SNCA Gene

  • Alpha-synuclein is a member of the synuclein family, which also includes beta- and gamma-synuclein. Synucleins are abundantly expressed in the brain and alpha- and beta-synuclein inhibit phospholipase D2 selectively. SNCA may serve to integrate presynaptic signaling and membrane trafficking. Defects in SNCA have been implicated in the pathogenesis of Parkinson disease. SNCA peptides are a major component of amyloid plaques in the brains of patients with Alzheimer's disease. Four alternatively spliced transcripts encoding two different isoforms have been identified for this gene. [provided by RefSeq, Mar 2009]

GeneCards Summary for SNCA Gene

SNCA (Synuclein, Alpha (Non A4 Component Of Amyloid Precursor)) is a Protein Coding gene. Diseases associated with SNCA include dementia, lewy body and parkinson disease 4. Among its related pathways are Disease and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include calcium ion binding and phospholipid binding. An important paralog of this gene is SNCB.

Post-translational modifications for SNCA Gene

  • Acetylation at Met-1 seems to be important for proper folding and native oligomeric structure.
  • Hallmark lesions of neurodegenerative synucleinopathies contain alpha-synuclein that is modified by nitration of tyrosine residues and possibly by dityrosine cross-linking to generated stable oligomers
  • Phosphorylated, predominantly on serine residues. Phosphorylation by CK1 appears to occur on residues distinct from the residue phosphorylated by other kinases. Phosphorylation of Ser-129 is selective and extensive in synucleinopathy lesions. In vitro, phosphorylation at Ser-129 promoted insoluble fibril formation. Phosphorylated on Tyr-125 by a PTK2B-dependent pathway upon osmotic stress.
  • Ubiquitinated. The predominant conjugate is the diubiquitinated form (By similarity).
  • Glycosylation at Thr54
  • Modification sites at PhosphoSitePlus

UniProtKB/Swiss-Prot

SYUA_HUMAN
  • Note=Genetic alterations of SNCA resulting in aberrant polymerization into fibrils, are associated with several neurodegenerative diseases (synucleinopathies). SNCA fibrillar aggregates represent the major non A-beta component of Alzheimer disease amyloid plaque, and a major component of Lewy body inclusions. They are also found within Lewy body (LB)-like intraneuronal inclusions, glial inclusions and axonal spheroids in neurodegeneration with brain iron accumulation type 1.
  • Parkinson disease 1 (PARK1) [MIM:168601]: A complex neurodegenerative disorder characterized by bradykinesia, resting tremor, muscular rigidity and postural instability. Additional features are characteristic postural abnormalities, dysautonomia, dystonic cramps, and dementia. The pathology of Parkinson disease involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain. The disease is progressive and usually manifests after the age of 50 years, although early-onset cases (before 50 years) are known. The majority of the cases are sporadic suggesting a multifactorial etiology based on environmental and genetic factors. However, some patients present with a positive family history for the disease. Familial forms of the disease usually begin at earlier ages and are associated with atypical clinical features. {ECO:0000269 PubMed:23427326, ECO:0000269 PubMed:23457019, ECO:0000269 PubMed:24936070, ECO:0000269 PubMed:25561023, ECO:0000269 PubMed:9197268, ECO:0000269 PubMed:9462735}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Parkinson disease 4 (PARK4) [MIM:605543]: A complex neurodegenerative disorder with manifestations ranging from typical Parkinson disease to dementia with Lewy bodies. Clinical features include parkinsonian symptoms (resting tremor, rigidity, postural instability and bradykinesia), dementia, diffuse Lewy body pathology, autonomic dysfunction, hallucinations and paranoia. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Dementia Lewy body (DLB) [MIM:127750]: A neurodegenerative disorder characterized by mental impairment leading to dementia, parkinsonism, fluctuating cognitive function, visual hallucinations, falls, syncopal episodes, and sensitivity to neuroleptic medication. Brainstem or cortical intraneuronal accumulations of aggregated proteins (Lewy bodies) are the only essential pathologic features. Patients may also have hippocampal and neocortical senile plaques, sometimes in sufficient number to fulfill the diagnostic criteria for Alzheimer disease. {ECO:0000269 PubMed:14755719}. Note=The disease is caused by mutations affecting the gene represented in this entry.
