Variant information Variant position: help 398 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 Serine (S) to Alanine (A) at position 398 (S398A, p.Ser398Ala). 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 small size and polar (S) to small size and hydrophobic (A) The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score: help 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).

Sequence information Variant position: help 398 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length: help 525 The length of the canonical sequence.
Location on the sequence: help DVSQFDSKFTRQTPVDSPDD S TLSESANQVFLGFTYVAPSV 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 – 525 Ribosomal protein S6 kinase beta-1
Domain 353 – 423 AGC-kinase C-terminal
Region 380 – 399 Disordered
Modified residue 394 – 394 Phosphoserine
Modified residue 412 – 412 Phosphothreonine; by MTOR, NEK6 and NEK7
Mutagenesis 394 – 394 S -> A. Loss of activity. Loss of phosphorylation at T-412.
Mutagenesis 412 – 412 T -> E. Mimics phosphorylation. Facilitates phosphorylation of T-252 by PDPK1; when associated with E-434; E-441; E-444 and E-447. Mimics phosphorylation. No effect on interaction with PDPK1 and phosphorylation of T-252. Impairs association with the eIF3 complex.
