中文摘要
该提案的目的是定义人类MAD 2(hsMAD 2)的功能
作为有丝分裂检查点基因,并确定hsMAD 2
有助于小鼠模型中瘤形成的产生。 hsMAD 2是
有丝分裂检查点基因的人类同源物,首次在出芽中鉴定
酵母(scMAD 2)。 研究者提出的检验假设是,
人MAD2检查点功能的生化机制是其
通过与Cdc16和Cdc27的相互作用抑制APC的能力。
此外,将在ES细胞和小鼠中破坏MAD 2,以确定
MAD2在哺乳动物有丝分裂检查点控制中作用
细胞
英文摘要
The aims of this proposal are to define how human MAD2 (hsMAD2) functions
as a mitotic checkpoint gene and to determine if disruption of hsMAD2
contributes to the generation of neoplasia in mouse models. hsMAD2 is the
human homolog of a mitotic checkpoint gene first identified in budding
yeast (scMAD2). The investigator proposes to test the hypothesis is that
the biochemical mechanism underlying human MAD2 checkpoint function is its
ability to inhibit the APC through its interactions with Cdc16 and Cdc27.
In addition, MAD2 will be disrupted in both ES cells and mice to determine
the contribution made by MAD2 to mitotic checkpoint control in mammalian
cells.
