Alternative products

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

Note: It is uncertain whether isoform ACYA is produced by alternative initiation or another biological event.

Isoform ACYB (identifier: P24540-1)

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 ACYA (identifier: P24540-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-2: Missing.

Note: Initiator methionine is removed. Contains an N-acetylalanine at position 2.
