Isoform 1 (identifier: P0DMS9-2) [UniParc]FASTA Add to basket

The sequence of this isoform can be found in the external entry P0DMS9.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.

Note: The first exon of TMIGD3 isoform 1 (i1) is shared with the first exon of ADORA3 isoform 2 (A3AR i2, commonly known as A3AR), resulting in a fusion protein.1 Publication
