Background: | C3a is a member of the anaphylatoxin family of three proteins (C3a, C4a and C5a) produced by the activation of complement. The des Arg form of C3a is an unglycosylated polypeptide. The activities of C3a are inactivated by removal of the C-terminal arginine. New activities have been identified for C3a des Arg acting through the C5L2 receptor. |
