General description

CD148, also known as Density-enhanced phosphatase 1 (DEP-1), is a membrane bound phosphatase that dephosphorylates a large number of protein targets and kinases thus serving as a regulator of many signaling cascades. CD148/DEP-1 plays a role in cell adhesion, migration, proliferation and differentiation. CD148/DEP-1 also plays a role in macrophage migration, adhesion and spreading. CD148/DEP-1 is also central to T-cell receptor signaling and acts as a negative regulator. CD148/DEP-1 acts as a positive regulator of endothelial cell survival and enhances the barrier function of epithelial junctions during reassembly. CD148/DEP-1 is also a key regulator of platelet activation and thrombosis as well as a tumor suppressor. CD148/DEP-1 is localized at the cell membrane particularly at cell projections, ruffle membranes, and cell junctions and it is expressed in lymphocytes and epithelial cells and expression increases as cell density increases.

Immunogen

His-tagged recombinant protein corresponding to Human CD148/DEP-1.

Quality

Evaluated by Western Blotting in HeLa cell lysate.

Western Blotting Analysis: 0.5 µg/mL of this antibody detected CD148/DEP-1 in 10 µg of HeLa cell lysate.

Target description

~260 kDa observed.
This protein is highly glycosylated and may run higher than the calculated molecular weight of 146 kDa (isoform 1) or 57 kDa (isoform 2). Uncharacterized bands may be observed in some lysates.

Physical form

Format: Purified
Protein A purified
Purified mouse monoclonal IgG1κ in buffer containing PBS without preservatives.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Vascularization defects in genetic recombinant mice have defined critical roles for a number of specific receptor tyrosine kinases. Here we evaluated whether an endothelium-expressed receptor tyrosine phosphatase, CD148 (DEP-1/PTPeta), participates in developmental vascularization. A mutant allele, CD148(DeltaCyGFP), was constructed to
