TAME hydrochloride 是后期促进复合体(APC/C 或 APC)的抑制剂,它与 APC/C 结合并阻止其通过 Cdc20 和 Cdh1 活化,产生有丝分裂阻滞。TAME hydrochloride 不能透过细胞膜。
生物活性 | TAME hydrochloride is an inhibitor ofanaphase-promoting complex/cyclosome (APC/C or APC), which binds to APC/C and prevents its activation by Cdc20 and Cdh1, produces mitotic arrest. TAME hydrochloride is not cell permeable[1][2]. |
IC50& Target | Anaphase-promoting complex (APC)[1] |
体外研究 (In Vitro) | The absence of APC substrates, TAME hydrochloride ejects Cdc20 from the APC by promoting Cdc20 auto-ubiquitination in its N-terminal region. Cyclin B1 antagonizes TAME hydrochloride's effect by promoting binding of free Cdc20 to the APC and suppressing Cdc20 auto-ubiquitination[2]. TAME hydrochloride stabilizes cyclin B1 inXenopusextract by two mechanisms. First, it reduces the kcatof the APCCdc20/cyclin B1 complex without affecting the Km, slowing the initial ubiquitination of unmodified cyclin B1. Second, as cyclin B1 becomes ubiquitinated, it loses its ability to promote Cdc20 binding to the APC in the presence of TAME hydrochloride. As a result, cyclin B1 ubiquitination terminates before reaching the threshold necessary for proteolysis[2].
