LZTR1 and infection: It is noteworthy that Beclin1 protein levels were higher in RSV-infected cells than in mock-infected cells at 0 h, a time point that represents a postadsorption stage following infection with RSV for 1.5 h, again consistent with early production of NS2 protein in infected cells due to the proximity of the NS2 gene near the RSV genome transcription start site (i.e., 3′ end of the RSV genome).
