Bathroom DIY Filter: Do we need to use cement board (backer board) for the walls around the bathtub/shower that we're going to retile?

Right now the tile is attached directly to the dry wall. We were planning on replacing most of that drywall with the mold resistant dry wall (I think that's called green board), but Home Depot and Lowes keep pushing the cement board for the part that we're going to tile (around the tub/shower).
Is it ok to use that drywall instead of the cement board (backer board)? If we use it, should we put RedGard on it (it's supposed to make it waterproof)?
