摘要
生长因子颗粒素蛋白前体(progranulin,PGRN)广泛存在于动物和植物组织中.研究证明,哺乳动物的PGRN是一个多功能分子,在组织/器官发育、细胞分化、肿瘤发生发展、炎症应答以及神经退行性疾病中均具有重要的作用.PGRN发挥生物学功能需要和多种结合蛋白相互结合,例如sortilin、Toll样受体9(TLR9)、肿瘤坏死因子受体(TNFR)及分泌性淋巴细胞蛋白酶抑制因子(SLPI)等.本文将对PGRN的结合受体和生物学功能进行综述.
The growth factor progranulin (PGRN) is widely expressed in animal and plant tissues.Previous studies showed that mammal' s PGRN has multiple functions and plays important roles in theregulation of tissue and organ development, cancer progression, cell differentiation, inflammationresponse and neuronal degeneration. PGRN exerts its function through associating with several bindingproteins, including sortilin, toll-like receptor 9 (TLR9) , tumor necrosis factor receptor (TNFR) andsecretory leukocyte peptidase inhibitor(SLPI). Here we review the biological significance of PGRN andits associated proteins.
