分子別名（Synonym）
PVR,FLJ25946,PVS,CD155,TAGE4,HVED,NECL5
表達區(qū)間及表達系統(tǒng)（Source）
Rhesus macaque CD155 Protein, Fc Tag (CD5-R5253) is expressed from human 293 cells (HEK293). It contains AA Asp 28 - Asn 343 (Accession # Q0MSE6-1).
Predicted N-terminus: Asp 28
蛋白結構（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 60.8 kDa. The protein migrates as 70-90 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
純度（Purity）
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景（Background）
CD155 is a Type I transmembrane glycoprotein in the immunoglobulin superfamily. Commonly known as Poliovirus Receptor (PVR) due to its involvement in the cellular poliovirus infection in primates, CD155's normal cellular function is in the establishment of intercellular adherens junctions between epithelial cells.
CD155/PVR was originally isolated based on its ability to mediate polio virus attachment to host cells. The fulllength (or CD155 alpha isoform) is synthesized as a 417 amino acid (aa) precursor that contains a 20 aa signal sequence, a 323 aa extracellular region, a 24 aa TM segment and a 50 aa cytoplasmic tail. The extracellular region contains one N terminal V type and two C2 type Ig like domains.
CD155 is a transmembrane protein with 3 extracellular immunoglobulin-like domains, D1-D3, where D1 is recognized by the virus. Low resolution structures of CD155 complexed with poliovirus have been obtained using electron microscopy while a high resolution structures of theectodomain D1 and D2 of CD155 were solved by x-ray crystallography.
