HSPA8 interacts with the N-terminal 19–272 amino acids of S1 subunit of IBV Beaudette, H120 and QX strains and M41-RBD interacts with HSPA8 of human and pig. (A–C) Detection of interaction between chicken HSPA8 and the N-terminal 19–272 amino acids of the S1 subunit of Beaudette (A), H120 (B), and QX (C) strains. 293T cells were cotransfected with indicated plasmids and then flag-tagged HSPA8 was immunoprecipitated with anti-flag antibody. The precipitated proteins were detected by Western blotting using anti-flag and anti-GFP antibodies. (D) Detection of the interaction between IBV M41-RBD and HSPA8 of human and pig. 293T cells were cotransfected with indicated plasmids and then flag-tagged HSPA8 was immunoprecipitated with anti-flag antibody. The precipitated proteins were detected by Western blotting using anti-flag and anti-GFP antibodies.
