Alternative products

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

Isoform 1 (identifier: Q9W1K5-1)

Also known as: A; B; C;

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: Q9W1K5-2)

The sequence of this isoform differs from the canonical sequence as follows:
     80-111: AAARHQCPYLVKRYEKEFINQGGDSAWLGGLD → SIFRLLFPTFISLPNWPKTIAIDWANEEHGLL
     112-497: Missing.

Note: No experimental confirmation available.

Isoform 3 (identifier: Q9W1K5-3)

The sequence of this isoform differs from the canonical sequence as follows:
     433-437: LLVRP → VRNQL
     438-497: Missing.

Note: No experimental confirmation available.
