Abstract:
:Certain physiological events in anterior pituitary tissue are regulated by protein kinase C that is relatively resistant to the inhibitor, H7. In the present studies we have shown that two H7-resistant protein kinase C activities may be isolated from (pituitary) gonadotroph-derived alpha T3-1 cells using hydroxyapatite chromatography. These activities have the characteristics of PKC zeta and an apparently novel PKC isoform. The availability of clonal alpha T3-1 cells will facilitate investigations of the pituitary events.
