Variant information Variant position: help 64 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant: help LP/P [Disclaimer] The variants are classified into three categories: LP/P, LB/B and US.
  • LP/P: likely pathogenic or pathogenic.
  • LB/B: likely benign or benign.
  • US: uncertain significance

Residue change: help From Glutamate (E) to Aspartate (D) at position 64 (E64D, p.Glu64Asp). 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: help Similar physico-chemical property. Both residues are medium size and acidic. The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score: help 2 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).

Variant description: help In PARK7; no apparent effect on protein stability; impaired mitochondrial morphology; no effect on detoxification activity on methylglyocal-adducted CoA. Any additional useful information about the variant.
Other resources: help Links to websites of interest for the variant.


Sequence information Variant position: help 64 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length: help 189 The length of the canonical sequence.
Location on the sequence: help VQCSRDVVICPDASLEDAKK E GPYDVVVLPGGNLGAQNLSE 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.
Sequence annotation in neighborhood: help 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.
TypePositionsDescription
Modified residue 67 – 67 Phosphotyrosine
Lipidation 46 – 46 S-palmitoyl cysteine
Lipidation 53 – 53 S-palmitoyl cysteine
Mutagenesis 46 – 46 C -> A. Reduces protein stability. No effect on oxidation.
Mutagenesis 46 – 46 C -> A. Reduces protein stability. No effect on oxidation. Reduced localization in lipid rafts; when associated with A-106.
Mutagenesis 46 – 46 C -> S. No effect on mitochondrial translocation neither on deglycase activity.
Mutagenesis 51 – 51 V -> A. Disrupts dimer formation and strongly reduces ability to eliminate hydrogen peroxide.
Mutagenesis 53 – 53 C -> A. Strongly reduces chaperone activity and ability to eliminate hydrogen peroxide.
Mutagenesis 53 – 53 C -> S. No effect on mitochondrial translocation neither on deglycase activity.
