Protein Information
| Introduction |
Complement C4 is a non-enzymatic component of C3 and C5 convertases and thus essential for the propagation of the classical complement pathway. It plays important roles in immunity, tolerance, and autoimmunity with the other numerous components. Furthermore, it is a crucial factor in connecting the recognition pathways of the overall system instigated by antibody-antigen (Ab-Ag) complexes to the other effector proteins of the innate immune response. |
| Alternative Names |
Complement C4; Complement Component C4; Complement Component 4 ; C4 |
