Among these charge states, it appears that the +4 charge state of Hepcidin-I shows the highest peptide signal intensity, whereas hepcidin-M shows the most intense peptide signal when it is in the +5 charge state.

"Thanks to our work, we think the sex peptide signal goes to a region of the fly's brain that is the homolog of the hypothalamus, which has been know for many years to be central in controlling sexual receptivity in vertebrates," explained co-lead author Dr Mark Palfreyman of the Research Institute of Molecular Pathology in Vienna, Austria.
Mark Palfreyman, from Research Institute of Molecular Pathology in Vienna, expalined in another Neuron paper that according to them the sex peptide signal went to a region of the fly's brain that was the homolog of the hypothalamus, which has been know for many years to be central in controlling sexual receptivity in vertebrates.
To determine if a serine in place of Thr-262 could facilitate dropout of the unmodified peptide signal from the high molecular weight fraction, we mutated Thr-262 to a serine.
