Summary:Provided by the present invention are a fusion protein binding to a CD47 protein and an application thereof, wherein the fusion protein is capable of binding to a CD47 protein by using a KD value of 1x10-8M or lower. The fusion protein may specifically block the interaction between a CD47 protein and SIRPα without causing a blood coagulation reaction, and may further inhibit the growth and/or proliferation of tumors or tumor cells. La présente invention concerne une protéine de fusion se liant à une protéine CD47 et une utilisation associée, la protéine de fusion étant capable de se lier à une protéine CD47 en utilisant une valeur KD de 1x10-8M ou moins. La protéine de fusion peut bloquer de manière spécifique l'interaction entre une protéine CD47 et SIRPα sans provoquer de réaction de coagulation sanguine, et peut en outre inhiber la croissance et/ou la prolifération de tumeurs ou de cellules tumorales. 本发明提供了一种结合CD47蛋白的融合蛋白及其应用,所述融合蛋白能够以1×10 -8M或更低的KD值与CD47蛋白相结合。所述融合蛋白可特异性阻断CD47蛋白与SIRPα的相互作用,且不引起凝血反应,还可以抑制肿
