The acrosome reaction, exposes the inner acrosomal membrane to the outside. The junction between this inner acrosomal membrane and the sperm cell membrane is called the equatorial region, and this is where membrane fusion between sperm and egg begins

The magnitude of this dipole moment corresponds to about 0.5-0.7 unit charge at each end of the helix. These charges would be expected to attract ligands of opposite charge and negatively charged ligands, especially when they contain phosphate groups and frequently bind at the N-termini of a helices. In contrast, positively charged ligands rarely bind at the C-terminus

Like the Lambda repressor, the cII protein is a transcriptional activator. It binds to a site upstream of a promoter called PRE (for repressor establishment) and stimulates transcription of the cI (repressor) gene from that promoter.
