产品介绍
衰变加速因子(CD55)是血细胞膜上糖化磷脂酰肌醇(GPI)锚定蛋白,具有抑制补体系统激活,参与信号传递,有协助T淋巴细胞活化功能。
背景资料
This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade
蛋白名
Complement decay-accelerating factor
亚基
Monomer (major form) and non-disulfide-linked, covalent homodimer (minor form). Binds to coxsackievirus A21, coxsackieviruses B1, B3 and B5, human enterovirus 70, human echoviruses 6, 7, 11, 12, 20 and 21 capsid proteins and acts as a receptor for these viruses.
亚细胞定位
Isoform 1: Cell membrane; Single-pass type I membrane protein.
Isoform 2: Cell membrane; Lipid-anchor, GPI-anchor.
组织特异性
Expressed on the plasma membranes of all cell types that are in intimate contact with plasma complement proteins. It is also found on the surfaces of epithelial cells lining extracellular compartments, and variants of the molecule are present in body fluids and in extracellular matrix.
翻译后修饰
The Ser/Thr-rich domain is heavily O-glycosylated.
相似性
Belongs to the receptors of complement activation (RCA) family.
Contains 4 Sushi (CCP/SCR) domains.
