摘要 低密度脂蛋白受体相关蛋白5(low density lipoprotein receptor related protein,LRP5)是低密度脂蛋白受体相关蛋白家族成员之一,表达于人类多种组织细胞,以肝脏、胰腺最多.在骨中主要表达于骨内膜和骨小梁表面的成骨细胞,尚未发现在破骨细胞表达.LRP5与果蝇生长因子Wingless共受体Arrow序列同源,它是由1 615个氨基酸组成的跨膜蛋白,由一个假定的信号肽、4个表皮生长因子(epidermal growth factor,EGF)样重复序列、3个低密度脂蛋白受体(low density lipoprotein receptor,LDLR)重复序列跨膜区和胞内区部分组成.人LRP5进化高度保守,与小鼠LRP5的蛋白序列95%同源.
