Alternative products

This entry describes 3 isoforms produced by alternative splicing and alternative initiation. [Align] [Select]

Isoform Mitochondrial (identifier: O70325-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform Nuclear (identifier: Q91XR9-1)

The sequence of this isoform can be found in the external entry Q91XR9-1.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.

Isoform Cytoplasmic (identifier: O70325-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-27: Missing.

Notes: Produced by alternative initiation at Met-28 of isoform Mitochondrial.
