Subcellular localization of the catalytic subunit of protein kinase A (PKA) and its colocalization with the proteasome in human spermatozoa. Spermatozoa were incubated under capacitating conditions for 15 min. The cells were fixed and labelled with a PKA catalytic subunit primary antibody (red; [B]) and primary antibody against proteasomal subunit PSMA7 (green; [C]). DIC: differential interference contrast. Scale bar is 5 μm in all photos.
