ID Conversion within ENSEMBL?

Question

[bbmisraccb]

Hello,

I have these ENSEMBL IDs: ENSCSAG00000010073, ENSCSAG00000013647 and so on for 1000s. These are different from the regular human =Ensembl identifiers (ENSG, ENST, ENSP) for gene, transcripts, proteins etc. My species is CS so that is understandable- but how to get the identifiers for the human ensemble equivalents? What does "AG" stand for?

Regular ID Conversion tools would not do that like Uniprot mapping, Biomart is down for sometime, DAVID did not! Any web servers to do that ?

Thanks, Biswa

The 'formula' for Ensembl stable IDs takes into account the name of species where the gene is annotated (apart from human). So ENSCSAG00000010073 can be broken down as ENS (Ensembl) + CSA (the 3 letter code for the species name, in latin. In this case CSA stands for Chlorocebus sabaeus*) + G (for gene) +11 digit number (00000010073). If you want to find the orthologues in human for the vervet AGM, you can use BioMart. This is working fine for me now. If you are using the US mirror and having problems with that tool, try the main Ensembl site.
