Localization of calmodulin positive immunoreactivity in the surface epidermis of the brown trout, Salmo trutta

Summary

Calmodulin is a Ca2+-dependent modulatory protein which is required in the general regulation of a large number of key processes of cellular metabolism. In the present study, the localization of calmodulin positive immunoreactivity in the epidermis of the brown trout, Salmo trutta was investigated using a specific mouse monoclonal antibody to calmodulin of IgG2 class. The immunoreaction was found only in the superficial epithelial cells that constitute the main histological site for the production of calmodulin positive substances. Because of its distribution, this protein might have a physiological significance in the activation of the microvillar skeleton and in the control of the permeability of the skin epithelium.
