following studies on calcium transport by isolated smooth endoplasmic reticulum from unfertilized sea urchin eggs ( oberdorf , j. a. , head , j. f. , and kaminer , b . ( 1986 ) j. cell biol . 102 , 2205-2210 ) we have purified and partially characterized a calsequestrin-like protein from this organelle isolated from eggs from strongylocentrotus droebachiensis and arbacia punctulata .
