Isoform 2 (identifier: Q9NY97-2) [UniParc]FASTAAdd to Basket

The sequence of this isoform differs from the canonical sequence as follows:
     1-11: MSVGRRRIKLL → MVSRSLV

Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. No experimental confirmation available.
