中文名称

丙氨酸分解代谢

通路描述

在许多哺乳动物中,丙氨酸可通过线粒体 L-丙氨酸 3-脱氢酶(TDH)分解为乙酰辅酶 A 和甘氨酸(Dale 1978; Tressel 等 1986),或通过细胞质 L-丝氨酸脱氢酶/L-丙氨酸脱氨酶(SDS 和相关的 SDSL 蛋白)分解为 2-氧丁酸。大鼠肝脏的数据表明,两种途径的使用随生理状态而变化(Bird & Nunn 1983)。健康人类受体的研究表明,几乎所有的丙氨酸分解都遵循 2-氧丁酸途径(Darling 等 2000),这与人类基因组 TDH 基因编码的产物似乎会发生错误剪接且催化活性丧失的发现一致(Edgar 2002)。因此,人类丙氨酸降解在此处被注释为丙氨酸转化为 2-氧丁酸,以及 2-亚氨基丁酸转化为 2-氧丁酸的相关转化。
英文描述
NOTCH4 Intracellular Domain Regulates Transcription In the nucleus, NOTCH4 intracellular domain fragment (NICD4) binds transcription factors RBPJ (CSL) and mastermind family members (MAML1, MAML2 or MAML3) to form the NOTCH4 co-activator complex (Lin et al. 2002). The NOTCH4 coactivator complex stimulates transcription of well-established NOTCH targets HES1, HES5, HEY1 and HEY2 in a cellular context-dependent manner (Lin et al. 2002, Raafat et al.2004, Tsunematsu et al. 2004, Bargo et al. 2010). NOTCH4 also stimulates transcription of the FLT4 (VEGFR3) gene, encoding vascular endothelial growth factor receptor-3 (Shawber et al. 2007) and ACTA2 gene, encoding smooth muscle alpha actin (Tang et al. 2008).

NICD4 inhibits TGF-beta-induced SMAD-mediated transcription via binding of NICD4 to TGF-beta activated SMAD3 (Sun et al. 2005, Grabias and Konstantopoulos 2013).
