UniProtKB/Swiss-Prot Q9BXM7: Variant p.Gly386Ala

Serine/threonine-protein kinase PINK1, mitochondrial
Gene: PINK1
Chromosomal location: 1p36
Variant information

Variant position:  386
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  Disease [Disclaimer]
The variants are classified into three categories: Disease, Polymorphism and Unclassified.
  • Disease: Variants implicated in disease according to literature reports.
  • Polymorphism: Variants not reported to be implicated in disease.
  • Unclassified: Variants with uncertain implication in disease according to literature reports. Evidence against or in favor of a pathogenic role is limited and/or conflicting.

Residue change:  From Glycine (G) to Alanine (A) at position 386 (G386A, p.Gly386Ala).
Indicates the amino acid change of the variant. The one-letter and three-letter codes for amino acids used in UniProtKB/Swiss-Prot are those adopted by the commission on Biochemical Nomenclature of the IUPAC-IUB.

Physico-chemical properties:  Change from glycine (G) to small size and hydrophobic (A)
The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:  0
The score within a Blosum matrix for the corresponding wild-type to variant amino acid change. The log-odds score measures the logarithm for the ratio of the likelihood of two amino acids appearing by chance. The Blosum62 substitution matrix is used. This substitution matrix contains scores for all possible exchanges of one amino acid with another:
  • Lowest score: -4 (low probability of substitution).
  • Highest score: 11 (high probability of substitution).

Involvement in disease:  Parkinson disease 6 (PARK6) [MIM:605909]: An early-onset form of Parkinson disease, a neurodegenerative disorder characterized by parkinsonian signs such as rigidity, resting tremor and bradykinesia. A subset of patients manifest additional symptoms including hyperreflexia, autonomic instability, dementia and psychiatric disturbances. Symptoms show diurnal fluctuation and can improve after sleep. PARK6 pathogenesis involves respiratory complex I deficiency causing mitochondrial depolarization and dysfunction. Inheritance is autosomal recessive. {ECO:0000269|PubMed:15087508, ECO:0000269|PubMed:15349860, ECO:0000269|PubMed:15349870, ECO:0000269|PubMed:15505171, ECO:0000269|PubMed:15596610, ECO:0000269|PubMed:15955953, ECO:0000269|PubMed:15970950, ECO:0000269|PubMed:16009891, ECO:0000269|PubMed:16207217, ECO:0000269|PubMed:16207731, ECO:0000269|PubMed:16257123, ECO:0000269|PubMed:16401616, ECO:0000269|PubMed:16482571, ECO:0000269|PubMed:16632486, ECO:0000269|PubMed:16966503, ECO:0000269|PubMed:17030667, ECO:0000269|PubMed:18286320, ECO:0000269|PubMed:19229105, ECO:0000269|PubMed:20798600, ECO:0000269|PubMed:22043288, ECO:0000269|PubMed:22956510, ECO:0000269|PubMed:24652937, ECO:0000269|PubMed:24784582}.

Sequence information

Variant position:  386
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  581
The length of the canonical sequence.

Location on the sequence:   DNILVELDPDGCPWLVIADF  G CCLADESIGLQLPFSSWYVD
The residue change on the sequence. Unless the variant is located at the beginning or at the end of the protein sequence, both residues upstream (20) and downstream (20) of the variant will be shown.

Residue conservation: 
The multiple alignment of the region surrounding the variant against various orthologous sequences.

Sequence annotation in neighborhood:  
The regions or sites of interest surrounding the variant. In general the features listed are posttranslational modifications, binding sites, enzyme active sites, local secondary structure or other characteristics reported in the cited references. The "Sequence annotation in neighborhood" lines have a fixed format:
  • Type: the type of sequence feature.
  • Positions: endpoints of the sequence feature.
  • Description: contains additional information about the feature.
