The specific endocytosis of vitellogenin was measured in the presence of various concentrations of Stelazine, a specific inhibitor of the calcium regulating protein, calmodulin. Stelazine (200 microM) was found to inhibit the endocytosis of vitellogenin by 63% as determined by decreased uptake of vitellogenin into transitional yolk bodies and yolk platelets. The enzymatic activity of transglutaminase, a calcium-requiring enzyme implicated in receptor-mediated endocytosis, was not affected by these concentrations of Stelazine.
