Figure 2CLDN16 interacts with CLDN19 in yeast. (
A) Y2H assays showing interaction of CLDN16-WT with CLDN19-WT and CLDN19-WT with CLDN19-WT, but not of CLDN16-WT with CLDN16-WT. Shown are plates with selective medium lacking leucine and tryptophan (–LW), indicating the transforming of both bait and prey vectors; with SD-LWHA, indicating the expression of reporter genes
HIS3 and
ADE2; and β-galactosidase assay (A615 values) for quantification of interaction strength. (
B) Mutations in CLDN19 affecting its homomeric interaction. (
C) Mutations in CLDN19 affecting its heteromeric interaction with CLDN16. (
D) Mutations in CLDN16 affecting its heteromeric interaction with CLDN19.
