功能概要

该基因编码的蛋白质是一种线粒体蛋白质,具有两个假定结构域、一个 N 端线粒体定位序列和一个 UPF0099 结构域。体外试验表明,该蛋白质具有肽基-tRNA 水解酶活性,可从 tRNA 中释放肽基部分,从而防止可能降低翻译效率的解离肽基-tRNA 的积累。这种蛋白质还起到调节细胞存活和死亡的作用。作为附着在细胞外基质 (ECM) 上的细胞的整合素信号通路的一部分,它促进了存活,但也促进了失去与 ECM 附着的细胞的凋亡,这一过程称为 anoikos。在细胞失去对 ECM 的附着后,该蛋白质被磷酸化,从线粒体释放到细胞质中,并通过与转录调节因子的相互作用促进不依赖半胱天冬酶的细胞凋亡。该基因与肿瘤的发生和发展有关,并且该基因的突变与婴儿多系统神经、内分泌和胰腺疾病 (INMEPD) 相关,其特征是智力障碍、产后小头畸形、进行性小脑萎缩、听力障碍、多发性神经病、发育迟缓和器官纤维化伴有胰腺外分泌功能不全 (PMID: 25574476) 。可变剪接导致编码不同异构体的多个转录变体。[RefSeq 提供,2015 年 3 月]

The protein encoded by this gene is a mitochondrial protein with two putative domains, an N-terminal mitochondrial localization sequence, and a UPF0099 domain. In vitro assays suggest that this protein possesses peptidyl-tRNA hydrolase activity, to release the peptidyl moiety from tRNA, thereby preventing the accumulation of dissociated peptidyl-tRNA that could reduce the efficiency of translation. This protein also plays a role regulating cell survival and death. It promotes survival as part of an integrin-signaling pathway for cells attached to the extracellular matrix (ECM), but also promotes Apoptosis in cells that have lost their attachment to the ECM, a process called anoikos. After loss of cell attachment to the ECM, this protein is phosphorylated, is released from the mitochondria into the cytosol, and promotes caspase-independent Apoptosis through interactions with transcriptional regulators. This gene has been implicated in the development and progression of tumors, and mutations in this gene have been associated with an infantile multisystem neurologic, endocrine, and pancreatic disease (INMEPD) characterized by intellectual disability, postnatal microcephaly, progressive cerebellar atrophy, hearing impairment, polyneuropathy, failure to thrive, and organ fibrosis with exocrine pancreas insufficiency (PMID: 25574476). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2015]
