Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9LXI7-1)

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: Q9LXI7-2)

The sequence of this isoform differs from the canonical sequence as follows:
     338-385: SRVYQDKFDKCGPVYINIGDGGNLEGLATKYRDPNPEISLFREASFGH → VIECTKISSTNVVRFILTSEMVGI
     386-427: Missing.
Note: Derived from EST data. May be due to a competing donor splice site. No experimental confirmation available.
