ANXA2 is a receptor for YadC.
(a) Analysis of 5637 cell membrane proteins binding to HA-YadC by far western blotting and LC-MS/MS. The peptides detected and peptide coverage percentage of ANXA2 are shown. Detected peptides belonging to ANXA2 are indicated in red. (b) Co-immunoprecipitation analysis of the interaction between FLAG-YadC with ANXA2 in 5637 cells. α, anti-. (c) Co-immunoprecipitation analysis of the interaction between the purified ANXA2 and FLAG-YadC protein. (d) Immunofluorescence analysis of ANXA2 and HA-YadC localization in 5637 cells. Blue, nucleus; Green, ANXA2; Red, HA. Scale bar, 20 μm. (e) Immunofluorescence analysis of ANXA2 and E. coli localization in 5637 cells. Blue, nucleus; Red, LPS; Green, ANXA2. Scale bar, 8 μm.
