==SR Ca(2+)-ATPase in the HnE2 state complexed with the thapsigargin derivative Boc-12ADT.==
-
An analysis of the binding of the, 8-O-N-tert-butoxycarbonyl-12-aminododecanoyl derivative of, 8-O-debutanoylthapsigargin to the target molecule, the SERCA pump, has, revealed the importance of the length and flexibility of the side chain, attached to O-8. Based on the analysis a series of analogues to the, 2-unsubstituted analogue trilobolide has been constructed and shown to be, equipotent with thapsigargin as SERCA inhibitors. Only the, 12-Boc-aminododecaonoyl derivative, however, was found to be apoptotic.

== Function ==
 +
[https://www.uniprot.org/uniprot/AT2A1_RABIT 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).
