Glis2 interacts with BBS1, BBS2, and BBS11/TRIM32. FLAG-tagged BBS proteins (BBS1–12) were transiently co-transfected with V5.Glis2 into HEK 293T cells. After 24 h of transfection, cells were lysed, and FLAG-tagged BBS proteins were immunoprecipitated with FLAG-M2 beads. The precipitates were loaded onto 10% SDS gel and analyzed by Western blotting using anti-V5 and anti-FLAG antibodies. V5.Glis2 interacted with F.BBS1, F.BBS2, and F. BBS11/TRIM32, but not with the other BBS proteins. Antibody heavy chains were marked with HC. IP, immunoprecipitation; WB, Western blotting.
