IFITM3 (interferon induced transmembrane protein 3) is a transmembrane-domain protein (5-18kDa) belongs to a family of murine genes. It acts as a cellular restriction factor. It is associated with various cellular processes such as cell adhesion, immune-cell regulation, germ cell homing and maturation, and bone mineralization. It is involved in the inhibition of infection by influenza virus and many other pathogenic viruses.
Synonyms: Anti-Interferon-induced transmembrane protein 3; Anti-Interferon-inducible protein 1-8U
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: The activity of IFITM3 (interferon induced transmembrane protein 3) is post-translationally modulated by S-palmitoylation and lysine ubiquitination. IFITM3 shows controlled clustering in membrane compartments and antiviral activity against influenza virus in post S-palmitoylated condition. It has reported that S-palmitoylation positively regulates IFITM3 membrane affinity and antiviral activity. On the contrary, ubiquitination decreases localization with endolysosomes and decreases antiviral activity. It has also corroborated that gene silencing of IFITM3 plays an important role in glioma cell growth and migration. It can be used as a tumor biomarker as it possesses characteristics of inhibiting tumor development.
