the role of phospholipids in the interaction of fsh with receptors in the calf testis was explored by studying the effects of phospholipase-c ( pl-c ) on the binding of radioiodinated human fsh ( [ 125i ] iodo-hfsh ) to three previously characterized but different preparations of fsh receptor : a membrane fraction derived from calf testis homogenate , a buffer-soluble receptor present in the cytosol of the calf testis homogenate , and a detergent-soluble receptor prepared from the membrane fraction by extraction with triton x-100 .
