JAK1 and infection: As depicted in Figure 2, the PRV UL41 protein (Figure 2D), as well as the mRNAs of JAK1, Tyk2, STAT1, STAT2, and IRF9 (Figure 2E,F), were detectable in the RIP mixture, signifying that the mRNAs of JAK1, Tyk2, STAT1, STAT2, and IRF9 are among the targets of PRV UL41 during infection.
