Overview:
UBE2H or ubiquitin-conjugating enzyme E2H is a member of the E2 ubiquitin-conjugating enzyme family which is located on chromosome 7 (1). UBE2H is known to act on histones and cytoskeletal proteins, both involved in the degenerative pathway of the motor neuron. UBE2H expression is increased during erythroid differentiation of hCD34(+) cells. Tal1 transcription factor, which is essential for the development of the hematopoietic system and plays a role during definitive erythropoiesis in the adult, activates UBE2H expression, whereas Tal1 knock-down reduced UBE2H expression and ubiquitin transfer activity (2).
Gene Aliases:
E2-20K; UBC8; UBCH; UBCH2
Genbank Number:
NM_003344

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.
