The Sharingan is a special type of dojutsu (pupil technique) that naturally occurs in all members of the Uchiha clan, though not all of them gain the ability to utilize it. The Sharingan is thought to be descended from the Byakugan, but grants the user different abilities and a different insight.
However, transplanted eyes do not work as well in a non-Uchiha body, causing much more strain on the user, as is the case with Kakashi - extended use of his Sharingan will cause him to collapse. Uchiha clan members are not burdened with this weakness; while activation of the Sharingan does consume chakra, the drain is so small as to be almost insignificant.
