<p><b>New page</b></p><div>* Current Status<br />
<br />
Below are version 1 of some modENCODE ortholog resources. Its main page is http://www.modencode.org/ These are only for worm, fly and human. They do not yet completely use the [http://wiki.modencode.org/project/index.php/Reference_genes_and_transcripts Reference genes and transcripts]. <br />
The paper referring these builds can be found here http://papers.gersteinlab.org/<br />
<br />
Future plans involve making more use of the reference sets and incorporating yeast. <br />
<br />
* Cross Comparison Results '''(Use these!)''' <br />
<br />
We were able to use the different ortholog pairs and triplets that we had in order to look at how much overlap there was between the different ortholog resources. The file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/Results/human_fly.op.3 human_fly.op.3] contains the human-fly orthologs that are reported by all three ortholog resources. Similarly [http://archive.gersteinlab.org/proj/orthologs/Orthologs/Results/human_fly.op.2 human_fly.op.2] contains the human-fly ortholog pairs that have been reported in at least two of the aforementioned data resources. The file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/Results/human_fly.op.3 human_fly.op.1] has the human-fly ortholog pairs that were found in only one of the resources. The same analysis was done for the human-worm and worm-fly ortholog pairs, as well as the human-worm-fly triplets. '''Use the file containing all three resources for the list of most conservative ortholog pairs and triplets. The other files can be added if more pairs for the list are desired. The files are located below.''' <br />

<br />
Example of how the files were created:<br />
Suppose in Inparanoid we see an ortholog group that consists of 5 genes ''human-1, human-2, human-3, worm-1, fly-1''<br />
In TreeFam we see 4 of the 5 genes, ''human-1, human-2, worm-1, fly-1'' in the same ortholog group.<br />
In OrthoMCL none of the 5 genes exists in an ortholog group. These pairs and triplets would be assigned to the op.2 files<br />
<br />
We would build the following:<br />
<br />
2 human-worm-fly ortholog triplets assigned to op.2:<br />
(''human-1, worm-1, fly-1'')<br />
(''human-2, worm-1, fly-1'')<br />
<br />
2 human-worm ortholog pairs assigned to op.2:<br />
(''human-1, worm-1'')<br />
(''human-2, worm-1'')<br />
<br />
2 human-fly ortholog pairs assigned to op.2:<br />
(''human-1, fly-1'')<br />
(''human-2, fly-1'')<br />
<br />
1 worm-fly ortholog pair assigned to op.2:<br />
(''worm-1, fly-1'')<br />
In this case of worm-fly pair, the number of triplets is larger then the number of pairs<br />
<br />
If we change the assumption and an ortholog group exists in OrthoMCL that consists of ''human-1, human-2, worm-2''. There will be some changes in assignments from op.2 to op.3.<br />
<br />
We would build the following:<br />
2 human-worm ortholog pairs, assigned to op.3. There will be 0 pairs in op.2:<br />
(''human-1, worm-1'')<br />
(''human-2, worm-1'')<br />
<br />
2 human-worm-fly triplets, assigned to op.2:<br />
(''human-1, worm-1, fly-1'')<br />
(''human-2, worm-1 , fly-1'')<br />
<br />
2 human-fly ortholog pairs assigned to op.2:<br />
(''human-1, fly-1'')<br />
(''human-2, fly-1'')<br />
<br />
1 worm-fly ortholog pair assigned to op.2:<br />
(''worm-1, fly-1'')<br />
<br />
In summary, the "op.3" files means the ortholog pair exists in Inparanoid, OrthoMCL, and TreeFam, three independent ortholog resources, which would be the most conservative. If the op.1, op.2, op.3 were combined together, there would be more ortholog pairs. <br />

4. Based on these 3 tables, we built 12,336 human-fly ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/InParanoid/ip.raw.human_fly Inparanoid_raw_human_fly], 113,805 human-worm ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/InParanoid/ip.raw.human_worm Inparanoid_raw_human_worm] and 10,321 fly-worm ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/InParanoid/ip.raw.fly_worm Inparanoid_raw_fly_worm]. We also built 10594 worm_human_fly ortholog triplets in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/Triplet/IP.worm_human_fly.triplet IP.worm_human_fly.triplet]<br/><br />
5. There is an issue with the worm data file. It contains many more protein IDs, which leads to the higher number of worm ortholog pairs.<br />
Mapping to Reference Protein IDs and Summary:<br/><br />
To allow cross comparison, human and fly proteins IDs are mapped to the current Ensembl (53) protein IDs, and WormBase IDs are mapped to WormPep IDs, by using BioMart. If a human protein ID no longer exists in Ensembl, all ortholog pairs involved are removed. The ID mapping files are located under the head ID mapping at the end of the page. After mapping, we got 10,834 human-fly ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/InParanoid/IP.human_fly.pairs Inparanoid_human_fly_pairs], 96,724 human-worm ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/InParanoid/IP.human_worm.pairs Inparanoid_human_worm_pairs] and 8,876 fly-worm ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/InParanoid/IP.fly_worm.pairs InParanoid_fly_worm_pairs]. <br />

TreeFam was built on protein alignments. Based on the three files, our understanding is that each record is one transcription, and one gene could correspond to multiple transcripts, thus multiple records. We interpret one transcription as corresponding to one protein. <br />
<br />
2. [ftp://ftp.sanger.ac.uk/pub/treefam/release-7.0/MySQL/fam_genes.txt.table.gz fam_genes.txt.table.gz] presents the association of the genes’ family (both TreeFamA and TreeFamB). 803,408 genes were assigned to 16,141 gene families. Members of the same family should then be regarded as orthologs (together with in-paralogs). However, we found 204,845 IDs in this table that have no records in table genes.txt.table. We attached these 204,845 IDs in the file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.question_gfam.ids question_gfam.ids]. <br />

<br />
3.1 From table [ftp://ftp.sanger.ac.uk/pub/treefam/release-7.0/MySQL/fam_genes.txt.table.gz fam_genes.txt.table.gz]<br/><br />
Selecting from table [ftp://ftp.sanger.ac.uk/pub/treefam/release-7.0/MySQL/genes.txt.table.gz genes.txt.table.gz], the families containing human, fly and worm records (records are the total of 86,750 IDs), we got 8436 TreeFam families, and 7501 of them contains records from only one of the three species (this 8436 families are in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.human_fly_worm.fam_genes.raw human_fly_worm.fam_genes.raw].

We also built 10872 human-worm-fly triplets [http://archive.gersteinlab.org/proj/orthologs/Orthologs/Triplet/TF.worm_human_fly.triplet TF.worm_human_fly.triplet]. <br />
<br />
3.2 From [ftp://ftp.sanger.ac.uk/pub/treefam/release-7.0/MySQL/ortholog.txt.table.gz ortholog.txt.table.gz]<br/><br />
7,111,245 ortholog pairs are listed in this table, although we do not know how this table was created. From this table, we retrieved 15,004 human-fly ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.ortho_table.human_fly tf.ortho_table.human_fly], 14, 768 human-worm ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.ortho_table.human_worm tf.ortho_table.human_worm] and 12,544 fly-worm ortholog pairs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.ortho_table.fly_worm tf.ortho_table.fly_worm]. We did not do further filtering by the provided bootstrap value.<br />
<br />
Mapping to Ensembl Protein IDs and Summary:<br/><br />
We used data from 3.2 as ortholog pairs from TreeFam: 15,004 human-fly, 14,768 human-worm and 12,544 fly-worm gene pairs. This includes 12,146 human IDs, 8,557 fly IDs, and 7,778 worm IDs from table [ftp://ftp.sanger.ac.uk/pub/treefam/release-7.0/MySQL/genes.txt.table.gz genes.txt.table.gz]. Mapping the 12,146 human IDs to Ensembl protein ID (Ensembl 53, BioMart, transcript ID to protein ID), we got 11,433 Ensembl protein IDs in file [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.id_maping.human tf.id_mapping.human]. From 8,557 fly IDs, we got 4,588 fly Ensembl protein IDs (Ensembl 53, BioMart, Associated Transcript Name to protein ID, attached as [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.id_maping.fly tf.id_mapping.fly]. From 7,778 worm IDs, we got 6,308 WormBase peptide IDs (Ensembl 53, BioMart, transcript ID to WormPep ID, attached [http://archive.gersteinlab.org/proj/orthologs/Orthologs/TreeFam/tf.id_maping.worm tf.id_mapping.worm].
