D1S1733E,DAN,DAND1,NB,NO3

Catalog Number P10169-H08H
Organism Species Human
Host Human Cells
Synonyms D1S1733E,DAN,DAND1,NB,NO3
Molecular Weight The recombinant human DAN consists of 176 amino acids and has a calculated molecular mass of 19.3 kDa. As a result of glycosylation, rh DAN migrates as an approximately 27 kDa protein in SDS-PAGE under reducing conditions.
predicted N Ala 16
SDS-PAGE
Purity > 98 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the human DAN precursor (NP_005371.1) (Met 1-Asp 180) was expressed with a C-terminal polyhistidine tag.
Bio-activity Measured by its ability to inhibit BMP4-induced activity in MC3T3-E1 Mouse osteoblastic cells. The ED50 for this effect is typically 5-20 μg/ml in the presence of 50 ng/mL of recombinant human BMP4.
Research Area Cancer |Oncoprotein & suppressor & biomarker |Tumor biomarker |Tumor Suppressor |Other in Tumor suppressor
Formulation Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background The Dan (Differential screening-selected gene aberrative in neuroblastoma, also known as N03) gene was first identified as the putative rat tumor suppressor gene and encodes a protein structurally related to Cerberus and Gremlin in vertebrates. It is a founding member of the DAN family of secreted proteins, acts as an inhibitor of cell cycle progression and is closely involved in retinoic acid-induced neuroblastoma differentiation. There are at least five mammalian protein members in the evolutionarily conserved Dan family including DAN, Gremlin/DRM, Cer1 (Cerberus-related), Dante and PRDC (protein related to DAN and cereberus), and share the C-terminal cystine-knot motif. As a secreted glycoprotein, DAN is a member of a class of glycoproteins shown to be secreted inhibitors of the transforming growth factor-beta (TGF-beta) and bone morphogenic protein pathways. It binds to BMPs and preventing their interactions with signaling receptor complexes, and accordingly regulates the processes of embryonic development and tissue differentiation. DAN gene product may have an important role in regulation of the entry of cells into the S phase. In addition, DAN gene product possesses an ability to revert phenotypes of transformed rat fibroblasts and represents a candidate tumour suppressor gene for neuroblastoma.
