Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Isoform CGK1-beta (identifier: Q9Z0Z0-1)

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 CGK1-alpha (identifier: P0C605-1)

The sequence of this isoform can be found in the external entry P0C605-1.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.
