NuMA是核基质的一种组分,可能在间期核的结构中发挥结构作用。在细胞凋亡过程中,NuMA在细胞核内重新分布,并从238-kDa形式蛋白水解为180- 200-kDa形式。在这里,我们表明,导致稳定片段的切割位点发生在残基1701和1725之间。与细胞凋亡相关的形态学变化和NuMA的裂解都被TPCK处理延迟,但不被其他蛋白酶抑制剂包括ICE抑制剂II处理延迟。
NuMA is a component of the nuclear matrix which may play a structural role in the architecture of the interphase nucleus. During apoptosis NuMA is redistributed within the nucleus and is proteolysed from a 238-kDa form to a 180- to 200-kDa form. Here we show that the cleavage site leading to the stable fragment occurs between residues 1701 and 1725. Both the changes in morphology associated with apoptosis and the cleavage of NuMA were retarded by treatment with TPCK but not by treatment by other protease inhibitors including ICE inhibitor II.
