资源简介:
IRAK1 and 4 interact with Pellino-1 (Jiang et al. 2003), 2 (Strellow et al. 2003) and 3 (Butler et al. 2005, 2007). Pellinos may act as scaffolding proteins, bringing signaling complexes into proximity. They are E3 ubiquitin ligases capable of ubiquitinating IRAK1, believed to mediate IL-1-stimulated formation of K63-polyubiquitinated IRAK1 in cells.<br><br>Though not clearly demonstrated and therefore not shown here, the current models of IRAK1 involvement suggest it would be within a complex including TRAF6.
IRAΚ1与IRAΚ4相互作用于Pellino-1(Jiang等人,2003年)、Pellino-2(Strellow等人,2003年)以及Pellino-3(Butler等人,2005年,2007年)。Pellino蛋白可能充当支架蛋白,将信号复合物拉近。它们是E3泛素连接酶,能够泛素化IRAΚ1,据信介导细胞中IL-1刺激下K63多泛素化IRAΚ1的形成。<br><br>尽管尚未得到明确证实且因此在此未展示,关于IRAΚ1参与的当前模型表明,其可能位于包括TRAF6在内的复杂体中。
