What happens with milk proteins when being heated in a micro-wave oven?

Heating milk in a micro-wave oven does not modify the nutritional quality of its proteins, nor does it modify cells of its other constituents. The only precaution to take is verifying the temperature of the milk, which is often higher than the milk bottle or the cup. Also avoid putting the milk carton itself in the micro-wave oven as it contains an underlying layer of metal that can destroy the oven.
