UniProtKB/Swiss-Prot P10636: Variant p.Asn613His

Microtubule-associated protein tau
Gene: MAPT
Variant information

Variant position:  613
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 Asparagine (N) to Histidine (H) at position 613 (N613H, p.Asn613His).
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:  Similar physico-chemical property. Both residues are medium size and polar.
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).

Variant description:  In FTD; reduced the ability of tau to promote microtubule assembly without having a significant effect on tau filament formation; effects at both the RNA and the protein level.

Sequence information

Variant position:  613
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  758
The length of the canonical sequence.

Location on the sequence:   QIINKKLDLSNVQSKCGSKD  N IKHVPGGGSVQIVYKPVDLS
