t********9 发帖数: 536 | 1 各位大侠,我对基因方面懂得不多,现在有一个基因方面的问题向大家请教。我想找一
个基因tag-24 的promoter sequence,这个基因是c.elegans中的。下面是有关的信息
(包括了tag-24 的一个上游基因和一个下游基因)。请大侠帮忙算一下这个promoter
sequence 是多长呢?请讲讲是怎么算的。(因为tag-24 给的是complement, 我不知道
怎么办)(就按tag-24 得第一个isoform 为例吧。)多谢了!!!

| a***e 发帖数: 1010 | 2 go to wormbase.org
search tag-24
go to "location", click the picture, "Showing 2.515 kbp from X, positions 5,
608,905 to 5,611,419"
in "landmark or region", change "X:5608905..5611419" to "X:5608905..5613419"
In "reports & analysis", change to "download sequence files", click "go"
it will give you the 2k promoter plus the whole gene sequence. | a***e 发帖数: 1010 | 3 and for "tag-24", the upstream gene is 20kb away. | t********9 发帖数: 536 | 4 Thanks a lot Arche!!!
Could you let me know why I need to change "X:5608905..5611419" to "X:
5608905..5613419"in "landmark or region"?

| t********9 发帖数: 536 | 5 Arche. I think I know why I need to change the number.This way it will give
me 2 kb promoter sequence. Thanks!!!
However, do you or anyone know how to figure out the promoter sequence based
on the information from pubmed.com as I pasted in the first message?

| t********9 发帖数: 536 | 6 ahche, why I can not find the tag-24 gene sequence from the "2k promoter
plus the whole gene sequence"? tag-24 gene starts with atgtggaaccttaactg.....

| a***e 发帖数: 1010 | 7 you can download the cosmid sequence to your computer, and then according
to the position of tag-24 on that cosmid, you can select out the sequence
you need.
however, I never did that way. I prefer wormbase.

I really appreciate your help!!!
