Introduction
Complement component 1q, or C1q, is the first component of the classical pathway of the complement system. C1q is a subcomponent of the Complement component 1 (C1), along with C1r and C1s. The activation of C1q through the binding of the globular head (gC1q) to a variety of epitopes induces structural changes in the collogen-like region (CLR) of C1q. This activates C1r, which cleaves C1s, which splits into other complement proteins to further activate other aspects of the complement system. C1q binds to a variety of different antigens, such as phagocytes to induce phagocytosis, apoptotic cells through phosphatidylserine and DNA to induce apoptosis, and the Fc region of IgG and IgM to activate the complement system as described. C1q acts as a crucial protein that bridges the adaptive and innate immune system.
