资源简介:
The SUMO3 precursor has 11 extra residues at the C-terminus which can be removed endoproteolytically by SENP1, SENP2, or SENP5 (Zheng and Au, 2005, Gong and Yeh 2006, Mikolajczyk et al. 2007). The order of processing activity is: SENP1 greater than SENP2 greater than SENP5 (Mikolajczyk et al. 2007). Overall, processing of SUMO3 is the lowest of any SUMO (Mikolajczyk et al. 2007). SENP1 and SENP2 shuttle between the nucleus and cytosol and are predominantly nuclear (Bailey and O'Hare 2004, Kim et al. 2005, Zhang et al. 2002, Hang and Dasso 2002, Itahana et al. 2006). SENP5 is located in the nucleolus (Di Bacco et al. 2006, Gong and Yeh 2006).
SUMO3前体在C端额外拥有11个氨基酸残基,这些残基可通过SENP1、SENP2或SENP5(Zheng和Au,2005,Gong和Yeh,2006,Mikolajczyk等,2007)的内肽酶切割去除。其处理活性的顺序为:SENP1 > SENP2 > SENP5(Mikolajczyk等,2007)。总体而言,SUMO3的处理活性在所有SUMO蛋白中最低(Mikolajczyk等,2007)。SENP1和SENP2在细胞核与细胞质之间穿梭,主要定位于细胞核(Bailey和O'Hare,2004,Kim等,2005,Zhang等,2002,Hang和Dasso,2002,Itahana等,2006)。SENP5则位于核仁中(Di Bacco等,2006,Gong和Yeh,2006)。
