Analysis of Rab18 and a new golgin in the secretory pathway.
Two new amphibian genes have been isolated and characterized from frog melanotropes, and the level of expression of these genes is related to the secretory status of the cells. Both genes, Rab18 and a novel member of the golgin family of proteins, are ubiquitously expressed in endocrine and nonendocrine tissues, and their corresponding proteins appear to show intracellular distributions associated with discrete vesicular and tubular structures, respectively, suggesting that they may play relevant roles in the regulation of the secretory pathway.
