Calcium pump crystal structure with bound BeF3, TNP-AMP and TG in the absence of calcium

Template:ABSTRACT PUBMED 21239683

Function

[AT2A1_RABIT] This magnesium-dependent enzyme 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 (By similarity).
