Alternative products

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

Isoform 1 (identifier: O75363-1)

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 2 (identifier: O75363-2)

Also known as: 5B;

The sequence of this isoform differs from the canonical sequence as follows:
     309-309: T → TASKAESVCDGQAGQKTSEIQARGTKKKHLDSPRLGLAFRKFFRHK
     381-394: Missing.
     451-472: Missing.
     584-584: K → KYTGKCVFSHVKKKWPFQEWSY

Notes: May be phosphorylated on Ser-340.
