AXIN 的降解
中文名称
通路描述
AXIN 在细胞中含量较低,在 Xenopus 中被认为是β-猫enin 破坏复合物中的限制成分;但这可能不是哺乳动物细胞的情况(Lee 等人,2003;Tan 等人,2012)。细胞水平的 AXIN 部分通过泛素介导的周转进行调节。E3 连接酶 SMURF2 和 RNF146 均已被证明在促进 AXIN 通过 26S 蛋白酶体降解方面发挥作用(Kim 和 Jho,2010;Callow 等人,2011;Zhang 等人,2011)。
英文描述
Degradation of AXIN AXIN is present in low concentrations in the cell and is considered to be the limiting component of the beta-catenin destruction complex in Xenopus; this may not be the case in mammalian cells, however (Lee et al, 2003; Tan et al, 2012). Cellular levels of AXIN are regulated in part through ubiquitin-mediated turnover. E3 ligases SMURF2 and RNF146 have both been shown to play a role in promoting the degradation of AXIN by the 26S proteasome (Kim and Jho, 2010; Callow et al, 2011; Zhang et al, 2011).
