Organism
Porcine reproductive and respiratory syndrome virus (isolate Pig/United States/SD 01-08/2001)
Function
Major envelope protein present in abundant amounts in the virion envelope. Mediates virion sialic acid-dependent attachment the sialoadhesin receptor SIGLEC1. This attachment induces virion internalization into alveolar macrophages predominantly through clathrin-dependent endocytosis.
Similarity
Belongs to the arteriviridae GP5 protein family.
