CD47 Protein, Human (Biotinylated, HEK293, mFc-Avi)

CD47, an adhesive protein, facilitates cell-to-cell interactions and serves as a receptor for thrombospondin THBS1, modulating integrin signaling through the activation of heterotrimeric G proteins. Involved in diverse cellular processes, CD47 contributes to signal transduction, cardiovascular homeostasis, inflammation, apoptosis, angiogenesis, cellular self-renewal, and immunoregulation. Notably, it plays a role in modulating pulmonary endothelin EDN1 signaling and functions as a pressor agent in the regulation of blood pressure in response to THBS1. CD47 is crucial for memory formation and synaptic plasticity in the hippocampus, acting as a receptor for SIRPA and SIRPG, which impacts dendritic cell maturation, cytokine production, cell-cell adhesion, and T-cell activation. Furthermore, CD47 positively modulates FAS-dependent apoptosis in T-cells and suppresses angiogenesis, contributing to metabolic dysregulation during aging. In response to THBS1, CD47 negatively modulates wound healing, inhibits stem cell self-renewal, and may play a role in membrane transport and/or integrin-dependent signal transduction. As a monomer, CD47 interacts with THBS1, SIRPA, FAS/CD95, SIRPG, UBQLN1, UBQLN2, and potentially fibrinogen, highlighting its intricate involvement in cellular and molecular pathways.
