|complement component 3|
|Locus||Chr. 19 p13.3-13.2|
It is also an anaphylatoxin.
C3b may bind to microbial cell surfaces within an organism's body. This can lead to the production of surface-bound C3 convertase and thus more C3b components. Also known as C3bBb, this convertase is similar to soluble C3-convertase except that it is membrane bound.
C3b is cleaved into C3c and C3d.
