Answers.Text: I've tried it, but I look for a more "straightforward" method for displaying the genome locus for each protein. By the way, I've tried to use UCSC's Table Browser but couldn't query several genes simultaneously.

Answers.Text: I think that you will have to define "straightforward" if you want help.  BLAST and BLAT are the standard tools.  You need to describe what issues you have with those tools and what you would like instead.

Comments.Text: For something "straightforward" you'd need the correct reading frame, strand orientation, and splicing to get back to a nucleotide sequence to align to the genome. The tools mentioned should help take a lot of work out of this.

  I think the mistake here is thinking that you need to use the sequence in order to find the genome co-ordinates. If these proteins come from a well annotated speices, you can easily do this with BioMart.
  
  1. Go the the [ENSEMBL](http://www.ensembl.org/index.html) web site.
  2. From the top menu, select BioMart
  3. Under "-CHOSE DATABASE-" select Ensembl Genes, and under "-CHOOSE DATASET-" select your species (eg. Human Genes).
  4. Select "Filters" from the lefthand menu and then expand the "GENE" section.
  5. Select the "Input external references ID list [Max 500 advised]" and from the drop-down select "PDB IDs" or the correct "Uniprot KB" ID.
  6. Paste your IDs into the box.
  7. Select "Attributes" on the left-hand menu. Making sure you've the "Fetaures" radio box select, you can select Chromosome and either Gene Start/Gene End or Transcript start/Transcript end from the GENE section. These coordinates will also contain the untranslated regions unfortunately. You may also want to play about with the various things under "PROTEIN DOMAINS AND FAMILIES", particurlarly under "Protein Features", although I'm not sure what they all mean.
  8. When you are happy with the selection, select the big "Results" at the top to get the coords.
  
  You can also get out Sequences for both the full transcript and the CDS and known germline and somatic variants that fall within the boundaries of the genes.

  Have you tried [BLAST](https://blast.ncbi.nlm.nih.gov/blast/Blast.cgi), or specifically [tBLASTn](https://blast.ncbi.nlm.nih.gov/blast/Blast.cgi?PROGRAM=tblastn&PAGE_TYPE=BlastSearch&LINK_LOC=blasthome)? This will take a protein and compare it any set of reference genomes. You can also BLAST multiple sequences at once.
