For example, if and individual has normal C3/C4 values but a decreased CH50, that can indicate a terminal complement pathway deficiency while if one has low C3 and CH50 values that can indicate an autoimmune condition such as systemic lupus erythematosus.

The cleavage of the C4 results in C4b bearing a thioester functional group [-S-C(O)-]: work in the 1980s on C3, and then on C4, indicated the presence, within the parent C3 and C4 structures, of a unique protein modification, a 15-atom (15-membered) thionolactone ring serving to connect the thiol side chain of the amino acid cysteine (Cys) in a ...
Beta-2 comprises C3 (complement protein 3). It is raised in the acute phase response. Depression of C3 occurs in autoimmune disorders as the complement system is activated and the C3 becomes bound to immune complexes and removed from serum. Fibrinogen, a beta-2 protein, is found in normal plasma but absent in normal serum.
C3: In terms of deficiency of C3, it has been found that 17 mutations in the C3 gene cause problems with C3. This rare condition mutates or prevents C3 protein from forming, lowering the immune system's ability to protect. [17] C4: C4 deficiency is highly associated with systemic lupus erythematosus. [3]

C2b diffuses into the plasma as a protein inflammatory mediator while C2a remains attached with C4b, forming the C3-convertase (C4b2a). The function of the membrane-bound C3-convertase is the cleavage of many many molecules of C3 into C3a and C3b. C3a is a smaller fragment of C3 is a potent inflammatory mediator.
