Human Gene CANT1 (ENST00000392446.10) Description and Page Index
  Description: Homo sapiens calcium activated nucleotidase 1 (CANT1), transcript variant 1, mRNA. (from RefSeq NM_138793)
RefSeq Summary (NM_001159773): This protein encoded by this gene belongs to the apyrase family. It functions as a calcium-dependent nucleotidase with a preference for UDP. Mutations in this gene are associated with Desbuquois dysplasia with hand anomalies. Alternatively spliced transcript variants have been noted for this gene.[provided by RefSeq, Mar 2010].

DESCRIPTION: RecName: Full=Soluble calcium-activated nucleotidase 1; Short=SCAN-1; EC=; AltName: Full=Apyrase homolog; AltName: Full=Putative MAPK-activating protein PM09; AltName: Full=Putative NF-kappa-B-activating protein 107;
FUNCTION: Calcium-dependent nucleotidase with a preference for UDP. The order of activity with different substrates is UDP > GDP > UTP > GTP. Has very low activity towards ADP and even lower activity towards ATP. Does not hydrolyze AMP and GMP. Involved in proteoglycan synthesis.
CATALYTIC ACTIVITY: A nucleoside diphosphate + H(2)O = a nucleotide + phosphate.
COFACTOR: Calcium.
BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 6.8;
SUBUNIT: Monomer.
SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass type II membrane protein. Golgi apparatus, Golgi stack membrane; Single-pass type II membrane protein. Note=Processed form: Secreted.
TISSUE SPECIFICITY: Widely expressed.
PTM: N-glycosylated.
DISEASE: Defects in CANT1 are the cause of Desbuquois dysplasia (DBQD) [MIM:251450]. A chondrodysplasia characterized by severe prenatal and postnatal growth retardation (less than -5 SD), joint laxity, short extremities, progressive scoliosis, round face, midface hypoplasia, prominent bulging eyes. The main radiologic features are short long bones with metaphyseal splay, a 'Swedish key' appearance of the proximal femur (exaggerated trochanter), and advance carpal and tarsal bone age. Two forms of Desbuquois dysplasia are distinguished on the basis of the presence (type 1) or absence (type 2) of characteristic hand anomalies: an extra ossification center distal to the second metacarpal, delta phalanx, bifid distal thumb phalanx, and phalangeal dislocations.
MISCELLANEOUS: Not inhibited by azide.
SIMILARITY: Belongs to the apyrase family.
SEQUENCE CAUTION: Sequence=AAM94564.1; Type=Erroneous initiation;

ModBase Predicted Comparative 3D Structure on Q8WVQ1
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
