C3(补体成分3)是补体系统(Complement system)的核心蛋白,属于补体基因家族(Complement gene family)。补体系统是先天免疫的重要组成部分,通过"补体级联反应"(一系列有序的蛋白激活过程)参与病原体清除、炎症调节和组织修复。C3在肝脏中合成,以185kDa的无活性前体形式分泌,经蛋白酶切割后形成具有活性的α链和β链。其生物学功能包括:作为"补体激活枢纽",所有三条补体激活途径(经典途径、凝集素途径和旁路途径)都汇聚于C3的裂解;裂解产物C3a是重要的过敏毒素(anaphylatoxin,能引起炎症反应的分子),C3b则参与病原体的调理作用(opsonization,标记病原体便于吞噬细胞识别)和膜攻击复合物(MAC)的形成。主要作用位点在血浆和细胞表面。C3突变可导致功能异常,如C3缺乏症会增加化脓性细菌感染风险;而过度激活则与多种疾病相关,如非典型溶血尿毒综合征(aHUS)、年龄相关性黄斑变性(AMD)和系统性红斑狼疮(SLE)。C3过表达会加剧炎症和自身免疫反应,可能导致组织损伤;而低表达则削弱免疫防御能力。补体基因家族的共性在于它们编码的蛋白质大多以酶原形式存在,需激活后才能发挥功能,且多参与免疫防御和炎症反应。目前C3的中文译名"补体成分3"已广泛接受,无需额外标注英文。该基因的调控异常与多种炎症性和自身免疫性疾病密切相关,是补体靶向治疗的重要对象。

Complement component C3 plays a central role in the activation of complement system. Its activation is required for both classical and alternative complement activation pathways. A peptide (C3a) derived from the encoded protein has antimicrobial activity, so people with C3 deficiency are susceptible to bacterial infection. [provided by RefSeq, Nov 2014]

补体成分C3起着补体系统的激活中心作用。它的激活是必需的古典和替代的补体活化途径。从编码蛋白的肽(C3a的)具有抗菌活性,所以人与C3缺陷很容易受到细菌感染。 [由RefSeq的,2014年11月提供]
