Rabbit Recombinant Monoclonal Antibody

Brand:  Invitrogen™ MA551747

Product Code. 30088109

Description

This antibody binds the FG loop of the human CD47, which interacts with SIRP alpha and several other known CD47/SIRP alpha -blocking mAb. CD47 is broadly distributed on normal adult tissues, as well as ovarian tumors, and is especially abundant in some epithelia and the brain. IAP or integrin assocaited protein has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins. It further plays an important role in memory formation and synaptic plasticity in the hippocampus. It also acts as a receptor for SIRPA. Binding to SIRPA prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells.

CD47, known as integrin-associated protein (IAP), is a glycosylated transmembrane glycoprotein with five domains, expressed widely across hematopoietic cells like T and B cells, monocytes, platelets, and erythrocytes, as well as non-hematopoietic cells. It interacts with integrins such as CD51/CD61 and CD41/CD61, and serves as a receptor for thrombospondin, mediating bi-directional signaling that affects neural synaptic activity and macrophage phagocytosis. CD47 acts as a ligand for CD172a (SIRP alpha), an inhibitory receptor on macrophages, preventing phagocytosis of CD47-positive cells. This interaction influences cell migration, B cell adhesion, T cell activation, and neuronal development, particularly in synapse-rich brain and retina regions. It also modulates chondrocyte responses to mechanical signals. T cell expression of CD47 can lead to activation or apoptosis in the presence of thrombospondin. Monoclonal antibody stimulation of CD47 has been shown to induce CD4+CD25- suppressive activity and increase Foxp3 expression. CD47's role in membrane transport, signal transduction, and its broad tissue distribution highlight its significance in various physiological processes.
