Variant position: 303 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length: 401 The length of the canonical sequence.
Location on the sequence:
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.
Type Positions Description
1 – 401 Soluble calcium-activated nucleotidase 1
63 – 401 Lumenal
284 – 284 Calcium; via carbonyl oxygen
246 – 401 Missing. In isoform 2.
287 – 287 C -> S. Reduces GDPase and ADPase activities 1.3-fold.
301 – 301 R -> A. Reduces activity by 99%.
308 – 308 S -> C. Reduces GDPase activity 1.3-fold and ADPase activity 2-fold. Severe loss of dimer formation; when associated with S-287.
317 – 317 A -> C. Reduces GDPase activity 1.7-fold and ADPase activity 1.5-fold. Severe loss of dimer formation; when associated with S-287.
