The present disclosure relates to a configurable seat assembly for a vehicle, a vehicle having a configurable seat assembly, and a method of reconfiguring a configurable seat assembly. The first and second printed circuit boards are aligned with each other and a heat sink, such that the heat sink is thermally coupled with heat-generating electronic devices on both the first and second printed circuit boards. The spring is moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded. The second memory element stores a revised packet fragment. Receptors produced by the gene isolated by the method, particularly catalytic receptors, are also contemplated.
