  Domain Name: NTR_complement_C4
NTR/C345C domain, complement C4 subfamily; The NTR domain found in complement C4 is also known as the C345C domain because it occurs at the C-terminus of complement C3, C4 and C5. Complement C4 is a key player in the activation of the component classical pathway. C4 is cleaved by activated C1 to yield C4a anaphylatoxin, and the larger fragment C4b, an essential component of the C3- and C5-convertase enzymes. C4b binds covalently to the surface of pathogens through a reactive thioester. The role of the NTR/C345C domain in C4 (C4b) is unclear.
No pairwise interactions are available for this conserved domain.
