Overview:
TESK2 or testis-specific kinase 2 is a serine/threonine protein kinase that contains an N-terminal protein kinase domain and belongs to the TESK subgroup of the LIMK/TESK family of protein kinases. The kinase domain of TESK2 is structurally similar to the kinase domain of testis-specific protein kinase-1 and the LIM motif-containing protein kinases (LIMKs). TESK2 is predominantly expressed in testis and prostate and plays an important role in spermatogenesis (1). TESK2 phosphorylates cofilin specifically at Ser-3 and induces formation of actin stress fibers and focal adhesions (2).

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.
