PB0162 | P05156 | Complement factor I | CFI | AHUS3, ARMD13, C3BINA, C3b-INA, FI, IF, KAF | Homo_sapiens | The presence of these cofactors on healthy cells allows degradation of deposited C3b by CFI in order to prevent undesired complement activation, while in apoptotic cells or microbes, the absence of such cofactors leads to C3b-mediated complement activation and subsequent opsonization (PubMed:28671664). |
