Overview:
VLK or vertebrate lonesome kinase is a protein kinase which is first expressed in E-cadherin-positive anterior visceral endoderm and mesendoderm, and later its expression is confined to E-cadherin-negative mesenchyme. VLK regulates the rate of protein export from the Golgi and thereby plays an important role in the formation of functional stroma by mesenchymal cells (1). Targeted disruption of VLK leads to a defect in lung development and delayed ossification of endochondral bone. VLK deficient mice display neonatal lethality due to respiratory failure, with a suckling defect arising from a cleft palate. VLK is required for the appropriate timing of flat proliferative chondrocyte differentiation (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.
