Figure 4. SPE-36 localization in live spermatids and activated sperm.

SPE-36::GFP localizes to puncta in spermatids, consistent with SPE-36 being within MOs. (A) Spermatids from spe-36::gfp; him-5 males. (B) Spermatids from control him-5 males. In in vivo activated spermatozoa a signal is seen in both the cell body and along the edge of the pseudopod in sperm with SPE-36::GFP (C) that is absent in the him-5 controls (D).
