Also known as XMP
Summary
EMP2 (epithelial membrane protein 2, HGNC:3334) is a protein-coding gene on chromosome 16p13.13, encoding Epithelial membrane protein 2 (P54851). Functions as a key regulator of cell membrane composition by regulating protein surface expression.
This gene encodes a tetraspan protein of the PMP22/EMP family. The encoded protein regulates cell membrane composition. It has been associated with various functions including endocytosis, cell signaling, cell proliferation, cell migration, cell adhesion, cell death, cholesterol homeostasis, urinary albumin excretion, and embryo implantation. It is known to negatively regulate caveolin-1, a scaffolding protein which is the main component of the caveolae plasma membrane invaginations found in most cell types. Through activation of PTK2 it positively regulates vascular endothelial growth factor A. It also modulates the function of specific integrin isomers in the plasma membrane. Up-regulation of this gene has been linked to cancer progression in multiple different tissues. Mutations in this gene have been associated with nephrotic syndrome type 10 (NPHS10).

Function. Functions as a key regulator of cell membrane composition by regulating protein surface expression. Also, plays a role in regulation of processes including cell migration, cell proliferation, cell contraction and cell adhesion. Regulates transepithelial migration of neutrophils into the alveolar lumen, potentially via mediation of cell surface expression of adhesion markers and lipid raft formation. Negatively regulates caveolae formation by reducing CAV1 expression and CAV1 amount by increasing lysosomal degradation. Facilitates surface trafficking and formation of lipid rafts bearing GPI-anchor proteins. Regulates surface expression of MHC1 and ICAM1 proteins increasing susceptibility to T-cell mediated cytotoxicity. Regulates the plasma membrane expression of the integrin heterodimers ITGA6-ITGB1, ITGA5-ITGB3 and ITGA5-ITGB1 resulting in modulation of cell-matrix adhesion. Also regulates many processes through PTK2. Regulates blood vessel endothelial cell migration and angiogenesis by regulating VEGF protein expression through PTK2 activation. Regulates cell migration and cell contraction through PTK2 and SRC activation. Regulates focal adhesion density, F-actin conformation and cell adhesion capacity through interaction with PTK2. Positively regulates cell proliferation. Plays a role during cell death and cell blebbing. Promotes angiogenesis and vasculogenesis through induction of VEGFA via a HIF1A-dependent pathway. Also plays a role in embryo implantation by regulating surface trafficking of integrin heterodimer ITGA5-ITGB3. Plays a role in placental angiogenesis and uterine natural killer cell regulation at the maternal-fetal placental interface, however not required in the maternal tissues for a viable pregnancy. Involved in the early stages of embryogenic development and cardiogenesis, potentially via regulation of epithelial-mesenchymal transition timing. May play a role in glomerular filtration.
Subunit / interactions. Interacts with PTK2; regulates PTK2 activation and localization. Interacts with ITGB3; regulates the levels of the heterodimer ITGA5-ITGB3 integrin surface expression. Interacts with P2RX7 (via C-terminus). Interacts with ITGB1; the interaction may be direct or indirect and ITGB1 has a heterodimer form.
Subcellular location. Golgi apparatus membrane. Cell membrane. Apical cell membrane. Membrane raft. Cytoplasm. Nucleus. Perinuclear region.
Tissue specificity. Expressed in ciliary body epithelia, sclera, cornea, and retinal pigment epithelium (at protein level). Expressed in lung and endometrial tissue; expression is particularly abundant in secretory endometrium (at protein level). Expressed in placental villous syncytiotrophoblasts and cytotrophoblasts and on the membrane of interstitial trophoblasts (at protein level).
Disease relevance. Nephrotic syndrome 10 (NPHS10) [MIM:615861] A form of nephrotic syndrome, a renal disease clinically characterized by focal segmental glomerulosclerosis, progressive renal failure, severe proteinuria, hypoalbuminemia, hyperlipidemia and edema. NPHS10 is a steroid-sensitive form characterized by onset in childhood and remission without end-stage kidney disease. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the PMP-22/EMP/MP20 family.
