Glycosyl-phosphatidylinositol-anchored and transmembrane forms of CD46 display similar measles virus receptor properties: virus binding, fusion, and replication; down-regulation by hemagglutinin; and virus uptake and endocytosis for antigen presentation by major histocompatibility complex class II molecules

糖基磷脂酰肌醇锚定型和跨膜型CD46均表现出相似的麻疹病毒受体特性：病毒结合、融合和复制；血凝素下调；以及病毒摄取和内吞作用，以便通过主要组织相容性复合体II类分子呈递抗原。
