Crystallization and Preliminary Crystallographic Analysis of Recombinant Human Calcyphosine

Human calcyphosine was cloned into the pET-28a vector and highly expressed in Escherichia coli BL21 (DE3) cells. The protein was purified and crystallized. The crystal diffracted to 2.8 Å and belonged to space group P21212, with the unit cell parameters a=70.39 Å, b=132.02 Å, c=46.20 Å.
