UniProtKB/Swiss-Prot P16473: Variant p.Asp36His

Thyrotropin receptor
Gene: TSHR
Variant information

Variant position:  36
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  Polymorphism
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 Aspartate (D) to Histidine (H) at position 36 (D36H, p.Asp36His).
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 medium size and acidic (D) to medium size and polar (H)
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).

Polymorphism:  The Asp727Glu polymorphism is associated with Graves disease in a Russian population. The Glu727 allele and the heterozygous Asp727Glu genotype are related to higher risk of the disease. The Asp727Glu polymorphism significantly ameliorates G(s)alpha protein activation in the presence of the gain-of-function mutation Ala593Asn although it is functionally inert in the context of the wild-type TSHR.

Sequence information

Variant position:  36
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  764
The length of the canonical sequence.

Location on the sequence:   PRDLGGMGCSSPPCECHQEE  D FRVTCKDIQRIPSLPPSTQT
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.
