Background
Complement component 1q (C1q) receptor 1 (C1qR1, also known as C1qRp, or cluster of differentiation 93-CD93) is a 126-kDa type 1 transmembrane glycoprotein expressed in endothelial and hematopoietic cells, and responsible for C1q-induced phagocytosis. CD93 contains one C-type lectin domain and five EGF-like domains. Mature human CD93 consists of a 557 amino acid (aa) extracellular domain (ECD) with one C‑type lectin domain, four tandem EGF‑like domains, and a mucin‑like domain, followed by a 21 aa transmembrane segment and a 51 aa cytoplasmic domain. CD93 is receptor for C1q, mannose-binding lectin (MBL2) and pulmonary surfactant protein A (SPA). Soluble CD93 promotes the differentiation of monocytes to macrophages, phagocytosis of apoptotic cells, and inflammatory responsiveness to multiple TLR ligands.
