Hi Vanessa, Thank you for your reply. However, this is not the answer to what I was asking for.
Let me make the question short and more clear: Question: I downloaded ENSEMBL transcripts from UCSC website using “tables” tab on 06/2011 (version 62 of ENSEMBL at that time). Would these transcripts I downloaded form UCSC already contain the correct coordinates for the rCRS chr M?" I just need a "yes" or "no" answer. Let me give you some information that may be useful for you to be able to answer this question more clearly: Facts: 1. The human MT genome has been replaced by the revised reference sequence (rCRS) NC_012920 (AC_000021) in Ensembl 57 (March 2010). See the news at the bottom of the page in the link below: http://mar2010.archive.ensembl.org/Homo_sapiens/Info/WhatsNew 2. So, any version of Ensembl after Ensembl version 57 would include the new rCRS chrM trancript coordinates. 2. UCSC genome browser has NOT converted to rCRS chrM sequence and is still using the old sequence for chrM. 3. UCSC genome browser currently provides "tables" tab for users to download ENSEMBL sequences. 4. It is not clear that if the users download the ENSEMBL transcripts from UCSC genome browser, will they get the new rCRS chrM coordinates or the old chrM coordinates for these ENSEMBL transcripts?? This is the issue. thanks, Laura ________________________________ From: Vanessa Kirkup Swing <[email protected]> To: Laura Smith <[email protected]> Cc: Brooke Rhead <[email protected]>; "[email protected]" <[email protected]> Sent: Thursday, March 22, 2012 11:26 AM Subject: Re: [Genome] ensemble version Hi Laura, Thank you for pointing out this issue.

I have a few more questions on the ENSEMBL transcripts that I downloaded from UCSC browser using "Tables" tab and would appreciate your feedback when you have a chance: 1. Are the ENSEMBL transcripts on chr M (Mitochondria) already mapped to rCRS chrM when someone uses the "Tables" tab on UCSC genome browser to download these transcripts? 2. I am aware of the note given on UCSC website on chrM: Note on chrM Since the release of the UCSC hg19 assembly, the Homo sapiens mitochondrion sequence (represented as "chrM" in the Genome Browser) has been replaced in GenBank with the recordNC_012920. We have not replaced the original sequence, NC_001807, in the hg19 Genome Browser. We plan to use the Revised Cambridge Reference Sequence (rCRS) in the next human assembly release. My question is: a. Does this note only apply to the genomic sequence? or b. Does it also apply to the ENSEMBL transcripts on UCSC genome browser? Can you please explain your answer to me in detail? I really want to understand this. The reason I am asking this is because the ENSEMBL annotation I see on UCSC browser seems to be for the rCRS version. However I am not sure. You will notice that in the old chrM (NC_001807) the first transcript starts at position 579. In the new rCRS chrM (NC_012920), transcript starts at 577 also this is displayed in UCSC genome browser as well. Please see the 3 links below and attached figures . http://genome.ucsc.edu/cgi-bin/hgTracks?hgsid=248088223&db=hg19&position=chrM%3A577-647 http://www.ncbi.nlm.nih.gov/nuccore/NC_001807.4?report=genbank http://www.ncbi.nlm.nih.gov/nuccore/NC_012920 Thank you, Laura ________________________________ From: Brooke Rhead <[email protected]> To: Laura Smith <[email protected]> Cc: "[email protected]" <[email protected]> Sent: Friday, March 16, 2012 2:41 PM Subject: Re: [Genome] ensemble version Hi Laura, For future reference, you can tell which Ensembl version is currently being displayed in the Ensembl Genes track by turning the track on in the Genome Browser. There will be a label above the items in the track (currently it says "Ensembl Gene Predictions - Ensembl 65"). Another way to find it is to click on any track item. The Ensembl version will be displayed at the top of the page, for example: "Ensembl Genes (ENST00000342992 - Ensembl 65)." The information you found in the release log is correct: you would have retrieved Ensembl version 62 data on 6/23/11. (Ensembl version 63 was released on 30 Sep 2011.) > Also, when I click on this webpage on the link for "ensemble version > 62", it takes me to ensemble version 65. Is this a bug? This is not exactly a bug. We generally only maintain one version of a track on the Genome Browser, and any link on the Release Log page will take you to that track. The information of what data was released on what date remains the same, however. Regarding the RefSeq track: the RefSeq track is updated daily in the Genome Browser. So, you would have downloaded whatever RefSeq Genes were available from Genbank as of 6/23/2011.
