The CD155 (acronym for Differentiation cluster 155 ), also called Poliovirus receptor It is a human protein, coded by the gene PVR . [first] [2]

The CD155 is a transmembrane glycoprotein of the surface of the immunoglobulins [3] Commonly known as Poliovirus receptor (PVR) due to its role in the infection of poliovirus in primates, although its physiological function is the formation of joint joints between epithelial cells. [4] The role of the CD155 in the immune system is not clear, although it seems to be involved in the humoral immune response in the intestine. [4]

The extracellular domain averages the cell adhesion to the vitronectin present in the extracellular matrix, while the intracellular domain interacts with the light chain of Dinein.

The CD155 is a transmembrane protein with 3 extracellular domains Ig-like , D1-D3, where the D1 is the one linked by the poliovirus. [5]

The low resolution of the complex CD155 with Poliovirus was obtained under the electronic microscope [5] While the high resolution structure of the D1 and D2 ectodini has been obtained by X -ray crystallography.
