Overview:
CAMKIβ is thought to be involved in a variety of developmental processes including development of the central nervous system (1). CAMKIβ2, an isoform of mCAMKIβ, is mainly present in the nervous system, including brain, spinal cord, trigeminal ganglion, and retina. Within the CNS, the expression of CAMKIβ2 is detected in the mantle zone suggesting its possible involvement in the differentiation of neurons (2).

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。
TERT是端粒酶逆转录酶
人的端粒酶是由端粒酶逆转录酶、端粒酶RNA和一种假尿嘧啶合成酶组成
