UniProtKB/Swiss-Prot Q99708: Variant p.Arg100Trp

DNA endonuclease RBBP8
Gene: RBBP8
Feedback?
Variant information Variant position: help 100 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 Arginine (R) to Tryptophan (W) at position 100 (R100W, p.Arg100Trp). 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 Change from large size and basic (R) to large size and aromatic (W) The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score: help -3 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 SCKL2. Any additional useful information about the variant.
Other resources: help Links to websites of interest for the variant.


Sequence information Variant position: help 100 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length: help 897 The length of the canonical sequence.
Location on the sequence: help LEDRLRAGLCDRCAVTEEHM R KKQQEFENIRQQNLKLITEL 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: help The multiple alignment of the region surrounding the variant against various orthologous sequences.

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
Chain 1 – 897 DNA endonuclease RBBP8
Region 45 – 160 Required for interaction with LMO4, probably by stabilizing the interaction through RPPB8 dimerization
Cross 115 – 115 Glycyl lysine isopeptide (Lys-Gly) (interchain with G-Cter in SUMO2)
Mutagenesis 89 – 89 C -> A. Reduces Zn(2+) content; when associated with A-92.
Mutagenesis 92 – 92 C -> A. Reduces Zn(2+) content; when associated with A-89.
Mutagenesis 115 – 115 K -> R. In K12R; defects in ability to promoting DNA resection and homologous recombination; when associated with R-62; R-78; R-132; R-133; R-404; R-572; R-578; R-640; R-759; R-760 and R-782. In K5R; defects in ability to promoting DNA resection and homologous recombination; when associated with R-62; R-78; R-132 and R-133.
