中文摘要：

核有丝分裂器蛋白（Nuclear Mitotic Apparatus Protein，NuMA）是一种在间期细胞核内有大量表达的大分子蛋白。NuMA是微管聚合因子，能使微管锚定于纺锤体极。在细胞有丝分裂，减数分裂过程中对纺锤体的形成和形态的雏持发挥重要作用。

英文摘要：

Nuclear Mitotic Apparatus （NuMA） Protein is a high molecular weight polypeptidean and is an abundant component of interphase nuclei. NuMA is a kind of microtubule polymerization factor that can tethering spindle microtubule to their poles. NuMA plays a role key in forms of spindle formation and maintenance.
