Isoform 1 (identifier: P00949-1)

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: P00949-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-13: MVKIVTVKTKAYP → MEEGPLPLLTIRTAPYH
     25-36: RVKVFQSSTNYA → KTYYFEDKPCYL
     44-56: ISTVEPAQRQEAT → FFSIDLKDRQGSS
     65-77: FYMKEAIQLIVRI → YFNKSAIETILQM

Notes: Localizes to the junctional skeletal sarcoplasmic reticulum, probably by association with phospholipids and/or other proteins.
