这个基因编码的蛋白质是肿瘤坏死因子受体超家族的一员。这种受体在胚胎发育过程中高度表达。它被证明与traf家族成员相互作用，并在细胞中过度表达时激活jnk信号通路。该受体通过caspase非依赖性机制诱导细胞凋亡，在胚胎发育过程中发挥重要作用。另外，还描述了编码不同亚型的剪接转录变体。[由RefSeq提供，2008年7月]
The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is highly expressed during embryonic development. It has been shown to interact with TRAF family members, and to activate JNK signaling pathway when overexpressed in cells. This receptor is capable of inducing apoptosis by a caspase-independent mechanism, and it is thought to play an essential role in embryonic development. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]
