Overview:
NEK 2 is closely related in its catalytic domain to the serine/threonine protein kinase NIMA of Aspergillus nidulans that is required for entry into mitosis and may function in parallel to the universal mitotic inducer p34cdc2. Like NIMA, the NEK2 protein is almost undetectable during G1 but accumulated progressively throughout S, reaching maximal levels in late G2 (1). NEK2 is shown to be expressed most abundantly in the testis of the adult tissues examined being localized to the nucleus (2).
Gene Aliases:
NLK1; HsPK21; NEK2A

提RNA一般注意:提取前材料的保存(新鲜材料,过夜处理的样品),提取中对外源性的RNA酶的清除控制(离心管,PCR管,电泳槽,台面等的无RNA酶化处理),提取后需要-80度保存.其次跑电泳时,注意电泳液最好用新鲜的,核酸染料等诸多因素.

对于外源性RNA酶的控制外源RNA酶清除剂,避免使用致癌物DEPC的危险方法就可简单操作清除耗材,台面,仪器等的外源RNA酶的降解作用.
