SEQUENCE SIMILARITIES

Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIA subfamily.

TISSUE SPECIFICITY

Skeletal muscle, fast twitch muscle (type II) fibers.

DEVELOPMENTAL STAGE

Isoform SERCA1A accounts for more than 99% of SERCA1 isoforms expressed in adult skeletal muscle, while isoform SERCA1B predominates in neo-natal skeletal muscle.

SUBCELLULAR LOCATION

Endoplasmic reticulum membrane. Sarcoplasmic reticulum membrane.

FUNCTION

Key regulator of striated muscle performance by acting as the major Ca2+ ATPase responsible for the reuptake of cytosolic Ca2+ into the sarcoplasmic reticulum. Catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Contributes to calcium sequestration involved in muscular excitation/contraction.
