General description
程序性细胞死亡1配体1(PD-L1),又称分化簇(CD274)或B7同源物1(B7-H1),是不断增长的B7免疫分子家族的成员。PD-L1是一种细胞表面免疫球蛋白,胞外区有两个Ig样结构域和一个短胞质结构域。该蛋白在心脏、骨骼肌、胎盘和肺中高表达,在胸腺、脾脏、肾脏和肝脏中弱表达。PD-L1在活化的T细胞、B细胞、树突状细胞、角质形成细胞和单核细胞上表达。编码它的基因位于人类染色体9p24.1。
Immunogen
根据NP_054862.1,在蛋白质序列的C末端具有序列CKKQSDTHLEETET的肽。
Biochem/physiol Actions
程序性细胞死亡1配体1(PD-L1)参与细胞和体液免疫反应的调节。PD-L1表达在脂多糖(LPS)和干扰素γ(IFNG)激活后的T细胞、B细胞、树突状细胞、角质形成细胞和单核细胞上上调,在表面Ig交联激活的B细胞中上调。PD-L1以白细胞介素-2依赖性方式和程序性细胞死亡1(PDCD1)非依赖性方式参与共刺激信号,该信号对T细胞增殖以及白细胞介素-10(IL10)和IFNG的产生至关重要。
