簡單介紹:
Human CD31 (PECAM1) protein (Recombinant) (Fc-Tag) (STJP000449)
詳情介紹:
Host: | HEK293 |
Note: | STRICTLY FOR FURTHER RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
Short Description: | Recombinant-Human CD31 (PECAM1)-Fc-Tag protein was developed from hek293 and has a target region of Fc-Tag. For use in research applications. |
Conjugation: | Unconjugated |
Formulation: | 0.2 Mu m filtered PBS solution, pH7.2. |
Storage Instruction: | Can be stored in working aliquots at 2°C-8°C C for one month, or at-20°C to-70°C for 1 year. Avoid repeated freeze/thaw cycles. NA |
Endotoxin: | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/μg (1EU/μg). NA |
Immunoreactivity: | Recombinant Human CD31 activity was determined by its ability to support the adhesion of Jurkat human leukemic T cells. When cells are added to recombinant human CD31 coated plates ( 3.3 Mu g/mL, 100 Mu L/well ) in the presence of PMA, approximately |
Gene Symbol: | PECAM1 |
Gene ID: | 5175 |
Uniprot ID: | PECA1_HUMAN |
Immunogen Region: | ECD |
Immunogen: | Optimized DNA sequence encoding extracellular domain of human CD31 including a C-terminal Fc tag was expressed in HEK293 cells. NA |
Tissue Specificity | Expressed on platelets and leukocytes and is primarily concentrated at the borders between endothelial cells. Expressed in human umbilical vein endothelial cells (HUVECs) (at protein level). Expressed on neutrophils (at protein level). Isoform Long predominates in all tissues examined. Isoform Delta12 is detected only in trachea. Isoform Delta14-15 is only detected in lung. Isoform Delta14 is detected in all tissues examined with the strongest expression in heart. Isoform Delta15 is expressed in brain, testis, ovary, cell surface of platelets, human umbilical vein endothelial cells (HUVECs), Jurkat T-cell leukemia, human erythroleukemia (HEL) and U-937 histiocytic lymphoma cell lines (at protein level). |
Post Translational Modifications | Phosphorylated on Ser and Tyr residues after cellular activation by src kinases. Upon activation, phosphorylated on Ser-729 which probably initiates the dissociation of the membrane-interaction segment (residues 709-729) from the cell membrane allowing the sequential phosphorylation of Tyr-713 and Tyr-690. Constitutively phosphorylated on Ser-734 in resting platelets. Phosphorylated on tyrosine residues by FER and FES in response to FCER1 activation. In endothelial cells Fyn mediates mechanical-force (stretch or pull) induced tyrosine phosphorylation. Palmitoylation by ZDHHC21 is necessary for cell surface expression in endothelial cells and enrichment in membrane rafts. |
Function | Cell adhesion molecule which is required for leukocyte transendothelial migration (TEM) under most inflammatory conditions. Tyr-690 plays a critical role in TEM and is required for efficient trafficking of PECAM1 to and from the lateral border recycling compartment (LBRC) and is also essential for the LBRC membrane to be targeted around migrating leukocytes. Trans-homophilic interaction may play a role in endothelial cell-cell adhesion via cell junctions. Heterophilic interaction with CD177 plays a role in transendothelial migration of neutrophils. Homophilic ligation of PECAM1 prevents macrophage-mediated phagocytosis of neighboring viable leukocytes by transmitting a detachment signal. Promotes macrophage-mediated phagocytosis of apoptotic leukocytes by tethering them to the phagocytic cells.PECAM1-mediated detachment signal appears to be disabled in apoptotic leukocytes. Modulates bradykinin receptor BDKRB2 activation. Regulates bradykinin- and hyperosmotic shock-induced ERK1/2 activation in endothelial cells. Induces susceptibility to atherosclerosis. Isoform Delta15: Does not protect against apoptosis. |
