Complement component C1q receptor (Cd93)

Receptor (or element of a larger receptor complex) for C1q, mannose-binding lectin (MBL2) and pulmonary surfactant protein A (SPA). May mediate the enhancement of phagocytosis in monocytes and macrophages upon interaction with soluble defense collagens.

May play a role in intercellular adhesion. Marker for early multipotent hematopoietic precursor cells.
