	~~== Function ==~~		A '''uniporter''' is a type of [[membrane transport protein]] that facilitates the movement of a single type of molecule or ion across a [[cell membrane]]. Unlike other transport proteins, uniporters do not couple the transport of the molecule to the movement of another molecule or ion. This process is known as [[facilitated diffusion]], and it allows substances to move down their concentration gradient without the input of energy.

	~~Uniporters function by binding to a molecule on one side~~ of ~~the cell membrane, undergoing a conformational change, and releasing the molecule on the other side~~ of ~~the membrane. This process is driven by the concentration gradient of the molecule being transported~~, ~~with the molecule moving from an area of high concentration to an area of low concentration~~. ~~This type of transport is known as [[facilitated diffusion~~]].

'''Uniporter''' is a type of [[protein]] that facilitates the transport of a single type of [[molecule]] across a [[cell membrane]]. This process is driven by the [[concentration gradient]] of the molecule being transported, and does not require the input of [[energy]].

== Function ==

Uniporters function by binding to a molecule on one side of the cell membrane, undergoing a conformational change, and releasing the molecule on the other side of the membrane. This process is driven by the concentration gradient of the molecule being transported, with the molecule moving from an area of high concentration to an area of low concentration. This type of transport is known as [[facilitated diffusion]].

== Types of Uniporters ==

There are several types of uniporters, each of which transports a specific type of molecule. These include:

* [[Glucose transporter]]s, which transport glucose across the cell membrane.
* [[Amino acid transporter]]s, which transport amino acids across the cell membrane.
* [[Nucleoside transporter]]s, which transport nucleosides across the cell membrane.

== Role in Disease ==

Mutations in the genes encoding uniporters can lead to a variety of diseases. For example, mutations in the gene encoding the glucose transporter GLUT1 can lead to [[GLUT1 deficiency syndrome]], a rare genetic disorder characterized by impaired glucose transport into the brain.
