Alternative products

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

Note: Additional isoforms seem to exist.

Isoform PDE1C2 (identifier: Q14123-1)

Also known as: HCam-3A;

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 PDE1C1 (identifier: Q14123-2)

Also known as: HCam-3B;

The sequence of this isoform differs from the canonical sequence as follows:
     631-634: GTKQ → DSQE
     635-709: Missing.
