I am currently reading a paper that makes a reference to the protein Aldolase A. More specifically, I am doing research on TF MEF2 binding sites, and the paper mentions that one binding site is located on the skeletal muscle-specific enhancer of Aldolase A. More specifically, the information is: Accession number X06351 with center 1985/1986.
So on NCBI, it leads me to this page: Accession X06351. Now, reading the pubmed abstract and going over the page there (keep in mind, I am not a biologist so I am not really sure what I am looking at half the time), I am under the impression that the sequence is only part of the actual gene for aldolase A and only shows non-coding exons (i thought exons are always coding).
So that's got me confused. Now, to clear my understand, I went to the actual Aldolase A 365 AA protein page. This really dosnt tell me anything so I click the link at the start of the page that says
DBSOURCE embl accession X12447.1
Clicking on this (which I presume leads me to the sequence that codes for this protein, correct?) leads me to this page. Okay so I though this page includes the ENTIRE sequence that codes for the protein. So somewhere in there, it must be that my original partial sequence (X06351) should be buried in there. But its not! So can someone explain what I am really looking at? What links did I actually follow?
An idea: I currently have an idea of my misunderstanding. If I recall correctly, the enhancer may be located relatively far away from the actual gene. Therefore, the DNA sequence from my accession X06351 may not actually be buried in the actual gene sequence.
A secondary question Is there a way to get to the enhancer/promoter regions for a gene from the NCBI page? For example, where can I get enhancer/promoter region information from the gene page of Aldolase A
