Question

[rajdeepboral00]

Hello all, I have used rsem for my isoform level detection and got multiple transcript ids for a single gene, for eg,

ENSMUST00000042296.9    ENSMUSG00000062078.16   Qki-201
ENSMUST00000097414.11   ENSMUSG00000062078.16   Qki-202
ENSMUST00000232721.2    ENSMUSG00000062078.16   Qki-203
ENSMUST00000233645.2    ENSMUSG00000062078.16   Qki-204
ENSMUST00000233684.2    ENSMUSG00000062078.16   Qki-205
ENSMUST00000233828.2    ENSMUSG00000062078.16   Qki-206

Here i am getting names of the transcripts like 201,202 and so on, but from here how will i know that which one is qki5 and which one is 7 and so. I have surfed ensembl much , can anyone please suggest me how can i get that infomation, its like the same for every genes.

It looks like Qki-204 (for qki5) if you cross-reference the transcript ID - UniProt ID - gene name. Step 1 - column 1 from the ensembl page; Step 2 - correlating to the uniprot ID
