C8 is made up of two peptide chains: C8β and C8αϒ. 

Binding of C8β to the C5b67 complex induces a conformational change in the C8 dimer such that the hydrophobic domain of C8αϒ can insert into the interior of the phospholipid membrane.

Feedback mechanisms suppress signaling by the PKA pathway:

1. Intrinsic GTPase activity of Gαs

2. PDE acts to hydrolyze cAMP to 5′-AMP

3. By BARK
