Overview:
PAD1 is a member of the peptidyl arginine deiminase family of enzymes, which catalyze the post-translational deimination of proteins by converting arginine residues into citrullines in the presence of calcium ions. PAD1 is a component of the 26S proteasome, a multiprotein complex that degrades proteins targeted for destruction by the ubiquitin pathway. The overexpression of PAD1 induced a distinctive pattern of multidrug resistance in mammalian cells and moderate resistance to ultraviolet light (1). PAD1 is also responsible for substrate deubiquitination during proteasomal degradation (2).
Gene Aliases:
HPAD10; PADI1; PDI; PDI1
Genbank Number:

最近遇到了实验上的大问题,就是用一步法做RNA的荧光定量PCR时,发现低浓度的做不出来,而DNA是可以的,想请问各位在一步法PCR中有没有什么高见,就是逆转录的Buffer有没有什么需要注意的地方!就是在逆转录酶的最适Buffer和Taq酶的最适Buffer中寻找一个最适的Buffer!

B、酶细胞产能细胞内(外)起作用消化酶细胞外起作用B错误;
C、酶同需要适条件同胃蛋白酶与胰蛋白酶所需PH同C错误;
D、葡萄糖细胞质基质解丙酮酸需要酶催化D确.
故选:D.
我是新手。我要开始做实验了,但一开始就碰到了个很大的问题。
我想买个能利用哺乳动物细胞RNA聚合酶将DNA转录成RNA的的质粒,向好几家公司打了电话,但都没有我想要的东西。
没有这个东西,我的实验就只能是蓝图了。哪位战友有办法的,能不能帮帮我?
不胜感激。
