OK thanks. Went through the drill and compared the mouse prestin with Trichoplaxproteins and the best fit was with two proteins that matched up 69 and 61 % with the mouse protein. That does seem like a fair amount of overlap.

In the light of Luthon's link to the ciliate nature of the animal's ventral side, I'm assuming that the proteins are actually being produced, and weren't just "theoretically" deduced from the genome.

So it looks as if a protein that was originally used for locomotion was called up for auditory duty in mammals?

Right, and you read my reply, studied all of those references and typed up a 60-plus word reply in, let’s see now, seven minutes and fifteen seconds, yes?

Hey, far be it from me to pretend that I can compete with such unparalleled genius.

Obviously not as brilliant as this "genius" >:D...

Perhaps more to do with sensing than locamotion? Still, this animal has no nervous system so the structures that carry out the sensing and relaying of information towards locamotion and other goal-directed behaviour seems like fascinating questions that needs to be answered... Who knows, maybe microtubules do somehow play a role in computing?

And perhaps quantum computing should not be dicarded just yet :P

The article above states that "Trichoplax adheres to the substrate as it moves propelled by its ventral cilia." In any case, it should be easy enough to verify under a microscope. And this protein is associated with cilia, not so? What makes you think that sensing may be involved?

Cilia are used for mechanosensing in your ears as well and Prestin plays its role there. Prestin has not been associated with any locomotion related functions.
