The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 15 - 20 µg/ml.
Use at an assay dependent concentration. Predicted molecular weight: 100 kDa.
FunctionCleaves a variety of phosphodiester and phosphosulfate bonds including deoxynucleotides, nucleotide sugars, and NAD.
Tissue specificityExpressed in bile ducts, prostate, uterus and colon. Exclusively expressed on basophils, mast cells and their progenitors.
Sequence similaritiesBelongs to the nucleotide pyrophosphatase/phosphodiesterase family. Contains 2 SMB (somatomedin-B) domains.
Post-translational modificationsN-glycosylation is necessary for correct trafficking to the apical surface, but is not the apical targeting signal. It has been suggested that the active SMB domain may be permitted considerable disulfide bond heterogeneity or variability, thus two alternate disulfide patterns based on 3D structures are described with 1 disulfide bond conserved in both.
Cellular localizationMembrane. Secreted. Located to the apical surface in intestinal and kidney epithelial cells. Located to the cell surface of basophils, and to the apical plasma membrane of bile duct cells. Secreted in serum, and in lumen of epithelial cells.
