Specific recombinant and synthetic peptide antibodies were used to examine the distribution of CaM kinases I and II in the rat pancreas and other tissues. The CaM kinase I antibodies detected a doublet of cytosolic proteins of \u223c38 and \u223c42 kD by immunoblot. CaM kinase I was observed in glucagon-containing A-cells at the periphery of the islet of Langerhans but had little or no overlap with pancreatic polypeptide or somatostatin cells. In contrast, CaM kinase II was localized to somatostatin-containing D-cells. CaM kinase I co-localized with glucagon secretory granules. CaM kinase II was not associated with the somatostatin granule but rather was enriched in areas of the cells that contained relatively little somatostatin. Because glucagon secretion is Ca\n                    <jats:sup>2+<\/jats:sup>\n                    -dependent, it is attractive to speculate that CaM kinase I may play a regulatory role in glucagon secretion.
