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

1 Jul 2001

Abstract excerpt

The amino terminus of the sperm cAMP-dependent protein kinase catalytic subunit (termed C(s)) differs from that of the Calpha1 isoform expressed in most tissues due to the use of alternative transcripts of the Calpha gene. Both Calpha1 and C(s) transcripts are present in testis; C(s) is expressed specifically in spermatogenic cells and is the only C isoform detected in mature sperm. Immunohistochemistry of mouse...
