UniProtKB/Swiss-Prot Q9NQV7: Variant p.Ser814Arg

Histone-lysine N-methyltransferase PRDM9
Gene: PRDM9
Variant information

Variant position:  814
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  LB/B
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 Serine (S) to Arginine (R) at position 814 (S814R, p.Ser814Arg).
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 small size and polar (S) to large size and basic (R)
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:  Several alleles exist depending on both the number of zinc finger C2H2 type domains and their identity (PubMed:26833727). Each allele binds to a specific hotspot set (PubMed:26833727). Variations in the zinc finger C2H2 type domains are associated with significant differences in affinity towards DNA-binding motif (PubMed:26833727). The sequence shown is that of allele B.
Additional information on the polymorphism described.

Variant description:  In allele L13; Increases affinity for the DNA-binding motif 5'-GCCTCCCTAGCCACG-3'.

Sequence information

Variant position:  814
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  894
The length of the canonical sequence.

Location on the sequence:   HQRTHTGEKPYVCRECGRGF  S NKSHLLRHQRTHTGEKPYVC
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.
