This family of ATPase membrane proteins are involved in [[Active Transport - Physiology#Secondary Active Transport|Secondary Active Transport]].  They bind two molecules and transport them accross the membrane either in the same direction ('''symporter''') or in opposite directions ('''antiporter''').  The [[Active Transport - Physiology#Development of Potential Energy|potential energy]] derived from forcing one molecule across this allows the other co-transported molecule to be transported against its gradient.
