Descripción
CDCP1 (CUB-domain containing protein 1), also known as Trask or CD318, is a type I transmembrane receptor whose specific role remains unclear. Human CDCP1 is synthesized with a large extracellular domain (ECD) containing three CUB domains, a transmembrane domain and a cytoplasmic domain with 5 tyrosine phosphorylation sites. CDCP1 was originally identified from proteins involved in metastasis and has been found on tumor, stem cells, keratinocytes and colonic epithelial cells. Tyrosine phosphorylation of the intracellular domain of CDCP1 results in downstream signaling through Src-family kinases (SFKs), Akt, and PKCδ. CDCP1 appears to be important for cell-cell and cell-substratum adhesion and the phosphorylation state of CDCP1 regulates this effect. CDCP1 is associated with a poor prognosis in epithelial tumors, such as lung, pancreatic, colorectal, renal, and ovarian carcinomas (rEf) and is a novel marker of the most aggressive human triple-negative breast cancers. Several different extracellular forms of CDCP1 have been shown to exhibit disease-specific expression in prostate cancer.

< 1.0 EU per 1μg of the protein by the LAL method. |
|
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
|
Reconstitution |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
Storage
Transported with ice packs. Store at -20℃ to -80℃, valid for one year.
After reconstitution, store unopened at -20 to -80°C for 3 to 6 months. After reconstitution, store at 2 to 8°C for 2 to 7 days.
It is recommended to store in aliquots and freeze for the first use to avoid repeated freezing and thawing.
