StAR protein has limited solubility and is mostly obtained through denaturation/refolding.

This is time-consuming, costly and may affect protein characteristics.

Fusing cleavable MBP to StAR confers its full solubility and facilitates purification.

The developed protocol results in native and aggregates-free StAR.

Capable of binding cholesterol, it is suitable for future investigations and biotechnology.
