NUMA1（nuclear mitotic apparatus protein 1），癌症关联基因，基因ID：4926，这个基因编码一个大蛋白，形成核基质的结构成分编码蛋白与微管相互作用，在细胞分裂过程中参与有丝分裂纺锤体的形成和组织。在急性早幼粒细胞白血病患者中检测到该基因与17号染色体上的rara（视黄酸受体，α）基因的染色体易位。选择性剪接导致多个转录变体[ RefSeq，2013月11日]This gene encodes a large protein that forms a structural component of the nuclear matrix. The encoded protein interacts with microtubules and plays a role in the formation and organization of the mitotic spindle during cell division. Chromosomal translocation of this gene with the RARA (retinoic acid receptor， alpha) gene on chromosome 17 have been detected in patients with acute promyelocytic leukemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq， Nov 2013]。
