产品介绍
Smac(second mitochondria-derived activator of caspase)又称DIABLO(direct IAP binding protein),是一种线粒体蛋白,也是重要的促细胞凋亡蛋白之一,能够促进细胞凋亡,当杀死不正常细胞的机制启动后,线粒体释放出Smac蛋白促使受损或不正常细胞凋亡的生化过程就会出现,Smac在诱导肿瘤细胞凋亡,增加肿瘤细胞的化疗敏感性及增强免疫力等方面有一定的意义和应用前景。Smac是第二个线粒体来源的胱氨酸酶激活剂,它通过拮抗或中和一种或几种凋亡抑制蛋白(IAP)家族成员而发挥其促凋亡作用。
背景资料
Promotes apoptosis by activating caspases in the cytochrome c/Apaf-1/caspase-9 pathway. Acts by opposing the inhibitory activity of inhibitor of apoptosis proteins (IAP). Inhibits the activity of BIRC6/bruce by inhibiting its binding to caspases.
蛋白名
Diablo homolog, mitochondrial
亚基
Homodimer. Interacts with NGFRAP1/BEX3 (By similarity). Interacts with BIRC2/c-IAP1, BIRC3/c-IAP2, XIAP/BIRC4, BIRC6/bruce and BIRC7/livin. Interacts with the monomeric and dimeric form of BIRC5/survivin.
亚细胞定位
Mitochondrion. Note=Released into the cytosol when cells undergo apoptosis.
组织特异性
Ubiquitously expressed with highest expression in testis. Expression is also high in heart, liver, kidney, spleen, prostate and ovary. Low in brain, lung, thymus and peripheral blood leukocytes. Isoform 3 is ubiquitously expressed.
翻译后修饰
Ubiquitinated by BIRC7/livin.
疾病
Deafness, autosomal dominant, 64 (DFNA64) [MIM:614152]: A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. Note=The disease is caused by mutations affecting the gene represented in this entry.
功能
Promotes apoptosis by activating caspases in the cytochrome c/Apaf-1/caspase-9 pathway. Acts by opposing the inhibitory activity of inhibitor of apoptosis proteins (IAP). Inhibits the activity of BIRC6/bruce by inhibiting its binding to caspases. Isoform 3 attenuates the stability and apoptosis-inhibiting activity of XIAP/BIRC4 by promoting XIAP/BIRC4 ubiquitination and degradation through the ubiquitin-proteasome pathway. Isoform 3 also disrupts XIAP/BIRC4 interacting with processed caspase-9 and promotes caspase-3 activation. Isoform 1 is defective in the capacity to down-regulate the XIAP/BIRC4 abundance.
