背景
功能:免疫球蛋白重链恒定区。免疫球蛋白,又称抗体,是由 B 淋巴细胞产生的膜结合或分泌型糖蛋白。在体液免疫的识别阶段,膜结合的免疫球蛋白作为受体,在与特定抗原结合后,触发 B 淋巴细胞的克隆扩增和分化,最终形成分泌免疫球蛋白的浆细胞。分泌型免疫球蛋白介导体液免疫的效应阶段,最终清除结合的抗原 (PubMed:20176268, PubMed:22158414)。抗原结合位点由一条重链的可变区及其对应的轻链的可变区共同构成。因此,每个免疫球蛋白都具有两个抗原结合位点,对特定抗原具有极高的亲和力。可变区通过称为 V-(D)-J 重排的过程组装而成,随后可发生体细胞高频突变,在接触抗原和选择后,可使抗体对特定抗原产生亲和力成熟 (PubMed:17576170, PubMed:20176268);分泌型 IgM (sIgM) 的恒定区,也称为 IgM 抗体的 Fc 区。sIgM 能够多聚化,形成高级聚合物,主要为五聚体,偶尔也形成六聚体,从而实现对抗原的多价性和高亲和力识别 (PubMed:32029689, PubMed:37095205)。天然 sIgM 具有多反应性,可识别保守的自身和病原体来源结构,而免疫 sIgM 仅在接触病原体后分泌,且具有抗原特异性。天然 sIgM 和免疫 sIgM 对于有效的体液免疫应答均是必需的 (基于相似性)。 sIgM 主要通过 Fc 受体和补体系统介导效应功能。在淋巴细胞上,它与高亲和力 Fc 受体 FCMR 结合,促进诱导有效的中和性 IgG 反应,同时维持对自身抗原的耐受性。它募集补体成分 C1q 启动经典补体途径,促进宿主识别和中和病原体。它与 C1q 和甘露糖结合凝集素共同促进巨噬细胞对凋亡细胞的吞噬作用,确保清除组织中潜在的自身免疫表位 (基于相似性)(PubMed:12847249, PubMed:19006321, PubMed:28230186, PubMed:32029689)。参与黏膜免疫。 IgM 通过 PIGR 介导的胞吞作用穿过黏膜上皮细胞,并与 PIGR 分泌成分形成复合物,分泌到顶端,用于扫描黏膜内层以寻找病原体。IgM-抗原复合物经 FCMR 介导的逆向胞吞作用,穿过黏膜 M 细胞到达黏膜淋巴组织中的抗原呈递细胞 (基于相似性)(PubMed:32029689);膜结合 IgM 的恒定区是 B 细胞受体复合物 (BCR) 的一部分。IgM BCR 为 B 细胞存活提供组成型持续信号。它介导 pre-BCR 信号,通过等位基因排斥调节 B 细胞选择和 Ig 基因重排。
亚细胞定位:分泌型;细胞膜;单次跨膜蛋白
异构体 & 翻译后修饰:P01871 有两种异构体:P01871-2:51924 Da (预测值);P01871-1:49440 Da (预测值)。
N-糖基化;对 IgM 的分泌及其在质膜上的定位至关重要。与 FCMR 的相互作用不依赖于糖基化修饰。
亚基:sIgM 和 mIgM 分子的基本结构单元均由两条相同的重链和两条相同的轻链组成,二者通过二硫键连接。重链和轻链的 N 端可变区构成抗原结合位点,而重链的 C 端恒定区与免疫受体相互作用,从而介导效应功能。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
