Differential Expression of the Cs and Cα1 Isoforms of the Catalytic Subunit of Cyclic 3′,5′-Adenosine Monophosphate-Dependent Protein Kinase in Testicular Cells1

Abstract
The amino terminus of the sperm cAMP-dependent protein kinase catalytic subunit (termed Cs) differs from that of the Cα1 isoform expressed in most ti
