UniProtKB/SwissProt variant VAR

Variant information

Variant position:

422

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

Type of variant:

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:

From Arginine (R) to Glutamine (Q) at position 422 (R422Q, p.Arg422Gln).

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 large size and basic (R) to medium size and polar (Q)

The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:

1

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).

Sequence information

Variant position:

422

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

Protein sequence length:

613

The length of the canonical sequence.

Location on the sequence:

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.

Type	Positions	Description
Chain	102 – 613	Apoptosis-inducing factor 1, mitochondrial
Region	134 – 483	FAD-dependent oxidoreductase
Binding site	438 – 438	FAD
Alternative sequence	44 – 613	Missing. In isoform 6.
Alternative sequence	325 – 613	Missing. In isoform 4.
Mutagenesis	413 – 430	EIDSDFGGFRVNAELQAR -> AIDSDFGGFAVNAELQAA. Disrupts dimerization. Lower efficiency in stabilizing charge-transfer complexes upon coenzyme reduction.
