&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Claudin&amp;#039;&amp;#039;&amp;#039; is a family of proteins that are integral to the formation of [[tight junctions]] in [[cellular biology]]. These proteins are crucial in maintaining the function of [[biological barrier]]s and [[cell polarity]]. &lt;br /&gt;
&lt;br /&gt;
== Structure ==&lt;br /&gt;
Claudins are composed of four [[transmembrane domain]]s, with the N-terminus and the C-terminus in the [[cytoplasm]]. They have two [[extracellular loop]]s, with the first one being larger and more variable. &lt;br /&gt;
&lt;br /&gt;
== Function ==&lt;br /&gt;
Claudins play a key role in the formation of tight junctions, which are crucial for the control of [[paracellular transport]] and the maintenance of cell polarity. They can form barriers that prevent the passage of solutes through the paracellular pathway, and they can also form pores that allow the selective passage of certain ions.&lt;br /&gt;
&lt;br /&gt;
== Clinical significance ==&lt;br /&gt;
Mutations in claudin proteins have been associated with a variety of diseases, including [[inflammatory bowel disease]], [[deafness]], and [[cancer]]. In particular, claudin-1 has been found to be a receptor for the [[hepatitis C virus]], and claudin-16 is involved in a form of [[familial hypomagnesemia]].&lt;br /&gt;
