General description

Leukocyte surface antigen CD47 (UniProt Q08722; also known as Antigenic surface determinant protein OA3, CD47, IAP, Integrin-associated protein, Protein MER6) is encoded by the CD47 (also known as MER6) gene (Gene ID 861) in human. Originally defined as a tumor-specific marker for ovarian carcinoma, CD47 a multitransmembrane glycoprotein widely expressed on all hematopoietic cells and most other cell types. CD47 plays a role in αvβ3-mediated cell adhesion and Ca2+ influx, as well as in platelet activation via interaction with thrombospondin-1. In addtion, CD47 modulates peripheral mononuclear (PMN) neutrophil migration across endothelial and epithelial monolayers. The rate of fMLP-stimulated PMN migration is shown to be decreased by CD47 functional blockage upon neutralizaing antibody treatment, which can be partially reversed by PI3K inhibition. Following fMLP stimulation and after PMN transmigration, secondary granules-derived CD47 molecules are shown to accumulate on plasma membrane, resulting in increased cell surface CD47 immunoreactivity. CD47 is produced with a signal peptide sequence (a.a. 1-18) that is removed posttranslationally to yiled the 5-transmembrane (a.a. 142-162, 177-197, 208-228, 236-256, 269-289) protein with its N-terminal end (a.a. 19-141), composed almost entirely of a V-type Ig-like domain (a.a. 19-127), exposed extracellularly and its C-terminal end (a.a. 290-323) at the cytoplasmic side.

Specificity

Clone PF3.1 detects human CD47 by targeting CD47 extracellular domain. In contrast to clone C5/D5 (Cat. No. MABF959), clone PF3.1 is suitable for immunoblotting, but not suitable for neutralizing CD47-dependent cellular signaling, while both clones can stain cell surface CD47 (Liu, Y., et al. (2001). J. Biol. Chem. 276(43):40156-40166).

Immunogen

CD47 purified from human spleen cells (Liu, Y., et al. (2001). J. Biol. Chem. 276(43):40156-40166).
Epitope: extracellular domain

Application

Immunoprecipitation Analysis: A representative lot immunoprecipitated an increased amount of surface CD47 from human polymorphonuclear (PMN) neutrophils following fMLP stimulation and after transmigration (Parkos, C.A., et al. (1996). J. Cell Biol. 132(3):437-450).

Western Blotting Analysis: A representative lot detected CD47 distribution among human polymorphonuclear (PMN) neutrophil subcellular fractions. Majority of CD47 was found co-localized with CD11b in the CD11b and secondary granules in unstimulated PMN and upregulated plasma membrane localization was seen following fMLP stimulation (Parkos, C.A., et al. (1996). J. Cell Biol. 132(3):437-450).
