TNFRSF1A
TNFR1属于肿瘤坏死因子(TNF)受体超家族成员之一,又称TNFRSF1A,CD120a或p55,是分子量为55kDa的I型跨膜糖蛋白。TNFR1包含胞外区、跨膜区和胞内区三个部分。胞外结构域含182个氨基酸,由4个富含半胱氨酸的结构域(CRD1-CRD2-CRD3-CRD4)组成。每个结构域包含6个保守半胱氨酸残基,含有3个N糖基化位点,其功能主要是与三聚体形式的TNF结合;跨膜区位于细胞外结构域和细胞内结构域之间,长约22个氨基酸;胞内结构域长约223个氨基酸。其中,在胞外结构域有3个潜在的N-糖基化位点,其功能主要是与三聚体形式的TNF结合。N末端残基是亮氨酸。C末端含有80个保守氨基酸序列所构成的死亡结构域(Death domain,DD),是转导细胞死亡信号所必需的,且TNFR1的很多功能都与此结构域有关。
TNFR1与TNF-α及TNF-β均有结合活性,有关TNFR1与TNF-α结合的研究比较多。当TNF-α与TNFR1 结合后一方面可以介导凋亡信号,引起细胞调亡,在抗肿瘤和抗病毒感染中发挥重要作用,同时也参与自身免疫性疾病和败血症中对自身组织细胞的损伤。TNFR1也可以介导细胞活化信号和增殖信号,诱导一氧化氮合成酶IL8的活性,活化核转录因子(NF-κB)和激活蛋白1。TNFR1还诱导细胞间粘附因子1和IL6的表达。作为一个热门的生物靶点,TNFR1具有双重作用,大量研究证实TNFR1的表达,能促进或抑制肿瘤细胞的凋亡,同时参与自身免疫性疾病。
