UniProtKB/Swiss-Prot Q92619: Variant p.Arg139His

Rho GTPase-activating protein 45
Gene: ARHGAP45
Feedback?
Variant information Variant position: help 139 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant: help 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: help From Arginine (R) to Histidine (H) at position 139 (R139H, p.Arg139His). 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 medium size and polar (H) The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score: help 0 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: help The HA-1H allele is presented on the cell surface and recognized by CTL, whereas the HA-1R allele is poorly represented by HLA-A and non-immunogenic, although HA-1R allelic frequency is the highest (PubMed:9820595, PubMed:16399573). Additional information on the polymorphism described.
Variant description: help In allele HA-1H; induction of CTL recognition for epitope HA-1. Any additional useful information about the variant.
Other resources: help Links to websites of interest for the variant.


Sequence information Variant position: help 139 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length: help 1136 The length of the canonical sequence.
Location on the sequence: help LLADVARFAEGLEKLKECVL R DDLLEARRPRAHECLGEALR 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.
Human                         LLADVARFAEGLEKLKECVLRDDLLEARRPRAHECLGEALR

Mouse                         LLADVARFAEGLEKLKECVLQDDLLEARRPLAHECLGEALR

Xenopus laevis                LLGDVARFAERLEKLRDVVQDEELKETRRPLAHECLGEALR

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.
