Intermembrane transfer of squalene promoted by supernatant protein factor

Supernatant protein factor (SPF), a protein that stimulates squalene epoxidation, mediates the transfer of squalene between two separable microsomal populations (Kojima, Y., E. J. Friedlander, and K. Bloch, 1981. J. Biol Chem. 256: 7235-7239). We now show that SPF also promotes the transfer of squal...

Both rough and smooth microsomes have squalene epoxidase activity that is stimulated by SPF.http://www.sciencedirect.com/science/article/pii/S0022227520379803
