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

Isoform 1 (identifier: Q68D86-1)

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.

Note: No experimental confirmation available.

Isoform 2 (identifier: Q68D86-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-216: Missing.
     479-483: LDDSL → VLLYE
     484-513: Missing.

Note: No experimental confirmation available.

Isoform 3 (identifier: Q68D86-3)

The sequence of this isoform differs from the canonical sequence as follows:
     286-311: ERLESALSLWKWKYEELKESKPKNVK → MEGKRNAHSFGKRNRETGVGFVSVEV
     422-424: ELL → DVK
