肿瘤坏死因子受体超家族成员21 (死亡受体6) (CD抗原CD358)

O75509

功能描述

促进细胞凋亡,可能通过涉及NF-kappa-B激活的途径。也能促进由BAX介导以及由细胞色素c从线粒体释放到细胞质所介导的细胞凋亡。营养因子剥夺触发β-分泌酶对表面APP的切割,释放sAPP-beta,后者被进一步切割以释放APP的N端片段(N-APP)。负向调节少突胶质细胞的存活、成熟和髓鞘形成。在由T细胞受体刺激触发的信号级联反应、适应性免疫应答以及T细胞分化和增殖的调节中发挥作用。负向调节T细胞反应以及Th2细胞释放IL4、IL5、IL10、IL13和IFNG等细胞因子。负向调节抗原应答中IgG、IgM和IgM的产生。可能抑制T细胞刺激应答中JNK的激活。还作为细胞焦亡的调节因子:响应活性氧(ROS)及其随后的氧化,募集CASP8,导致GSDMC的激活(PubMed:34012073)。 {ECO:0000269|PubMed:21725297, ECO:0000269|PubMed:22761420, ECO:0000269|PubMed:34012073, ECO:0000269|PubMed:9714541}。

组织特异性

Detected in fetal spinal cord and in brain neurons, with higher levels in brain from Alzheimer disease patients (at protein level). Highly expressed in heart, brain, placenta, pancreas, lymph node, thymus and prostate. Detected at lower levels in lung, skeletal muscle, kidney, testis, uterus, small intestine, colon, spleen, bone marrow and fetal liver. Very low levels were found in adult liver and peripheral blood leukocytes.
