Overview:
UBE2D3 also known as UBCH5C or ubiquitin-conjugating enzyme E2D3 is a member of the E2 ubiquitin-conjugating enzyme family which is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. UBE2D3 is involved in RA-induced cell cycle arrest and as a mediator of all-trans retinoic acid-induced cell growth arrest in human acute promyelocytic NB4 cells. UBE2D3 functions in the ubiquitination of the tumor-suppressor protein p53, which is induced by an E3 ubiquitin-protein ligase and is critical for normal cellular, tissue, and organismal physiology.
Gene Aliases:
E2(17)KB3, UBC4/5, UBCH5C
Genbank Number:
NM_003340

我在做5RACE,选用TaKaRa公司的RNA反转录酶(RNaseH-),不知道这个酶好不好,有什么需要注意的。
没有序列识别的功能,他就是简单的催化相邻DNA链的5-P末端和3'-OH末端以磷酸二酯键结合的反应,需ATP作辅酶。 不仅可以催化粘性末端之间或平滑末端之间的DNA的连接,也催化DNA与RNA之间以及少数RNA之间的连接。
反转录酶(Reversetranscripatase)是以RNA为模板指导三磷酸脱氧核苷酸合成互补DNA(cDNA)的酶。哺乳类C型病毒的反转录酶和鼠类B型病毒的反转录酶都是一条多肽链。鸟类RNA病毒的反转录酶则由两上亚基结构。真核生物中也都分离出具有不同结构的反转录酶。
