&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{DISPLAYTITLE:CD109}}&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;CD109&amp;#039;&amp;#039;&amp;#039; is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein that is a member of the α2-macroglobulin/C3, C4, C5 family of thioester-containing proteins. It is expressed on the surface of various cell types, including [[platelets]], activated [[T-cells]], and certain [[cancer]] cells. CD109 is involved in the regulation of [[transforming growth factor beta]] (TGF-β) signaling, which plays a crucial role in cell proliferation, differentiation, and immune responses.&lt;br /&gt;
&lt;br /&gt;
==Structure and Function==&lt;br /&gt;
CD109 is a large glycoprotein with a molecular weight of approximately 170 kDa. It is anchored to the cell membrane via a GPI anchor, which allows it to be released from the cell surface by phospholipase enzymes. The protein contains several domains, including a thioester bond that is characteristic of the α2-macroglobulin family.&lt;br /&gt;
&lt;br /&gt;
CD109 modulates TGF-β signaling by binding to TGF-β receptors and inhibiting their activity. This interaction can lead to the downregulation of TGF-β-mediated cellular responses, which is important in controlling cell growth and immune function. Dysregulation of CD109 expression or function has been implicated in various pathological conditions, including [[cancer]] and [[fibrosis]].&lt;br /&gt;
&lt;br /&gt;
==Expression and Clinical Significance==&lt;br /&gt;
CD109 is expressed in a variety of tissues, with high levels found in the [[skin]], [[lung]], and [[liver]]. It is also present on the surface of [[platelets]] and activated [[T-cells]]. In the context of cancer, CD109 expression has been observed in [[squamous cell carcinoma]], [[melanoma]], and other tumor types. Its role in cancer is complex, as it can both promote and inhibit tumor progression depending on the context.&lt;br /&gt;
&lt;br /&gt;
In addition to its role in cancer, CD109 has been studied in the context of [[autoimmune diseases]] and [[fibrotic disorders]]. Its ability to modulate TGF-β signaling makes it a potential therapeutic target for conditions characterized by excessive fibrosis or immune dysregulation.&lt;br /&gt;
&lt;br /&gt;
==Research and Therapeutic Potential==&lt;br /&gt;
Research on CD109 is ongoing, with studies focusing on its role in cancer biology, immune regulation, and tissue repair. The development of CD109-targeted therapies is an area of interest, particularly for diseases where TGF-β signaling is dysregulated. Potential therapeutic strategies include the use of antibodies or small molecules to modulate CD109 activity or expression.&lt;br /&gt;
