Honey bee mystery protein is a freight train for health and lifespan
Date:11/28/2011

cargo at different local stops or stations.

"I found out that, instead of starting the train journey from the fat cell main station, some vitellogenin molecules are divided in two, so the locomotive is separated from its cargo. The cargo cannot move without a locomotive and it stays in the fat cells, while the locomotive disappears. We soon realised that this is a typical behaviour for the vitellogenin molecule," Havukainen said.

Prior to this study, scientists believed vitellogenin to be one entity, like a cargo ship, unable to separate from its cargo. Therefore, Havukainen's new discovery is a big step forward for research that aims to keep bees healthy and long lived.

"We figured out that vitellogenin can drop its fat cargo as a reaction to changing chemical conditions. How this "drop" occurs and which factor makes the locomotive move and leave its cargo are important questions in the protein world, and probably equally important to the bee," Havukainen said.

What's up with the train hitch?

The research group believes that the separation of vitellogenin in two parts is a key to understanding how the protein works. They are now in search of the factor that breaks the fragile connection, or the train hitch of the protein, and lets the locomotive go.

"My discovery is that vitellogenin is not one entity. It consists of two functional parts. Now, I want to stop the separation process, so the locomotive and fat cargo are always together. This will help us figure out why the locomotive sometimes ditches its cargo and travels around on its own, and what the consequences are for the bees. This way, we can learn how vitellogenin affects social behaviour, immunity and stress resistance, and ultimately global food production and provision, Havukainen said.
