Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9BXI9-1)

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: Q9BXI9-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-1: M → MQWLRVRESPGEATGHRVTM
Isoform 3 (identifier: Q9BXI9-3)

The sequence of this isoform differs from the canonical sequence as follows:
     1-101: Missing.
     102-128: GPQGSKGDKGEMGSPGAPCQKRFFAFS → MSVGTSLEQAQMSTLTCPLFIPT
