[Demonstration of calmodulin in cultured human malignant melanocytes by indirect immunofluorescence].

Using calmodulin antibody, evidence for the presence of calmodulin, a calcium-binding protein modulator of numerous enzymes was shown by indirect immunofluorescence in 9 cell lines of cultured human malignant melanocytes. Calmodulin was localized in cytoplasm and in higher concentration in the perinuclear region. These observations agree with the distribution of calmodulin-binding proteins in cytoplasm and membranes.
