At later time points after infection, the SCV acquires certain characteristics of late endosomal/lysosomal compartments such as (i) the presence of a subset of Rab GTPases, such as Rab7, (ii) lysosomal glycoproteins (lgp), such as LAMP1, (iii) acidification, and (iv) juxtanuclear positioning. This evidence concerns the gene LAMP1 and infection.
