Figure 5. Subcellular localization and interaction of MTM-6A and MTM-9. (A) High-magnification confocal images of the GFP fusion protein expressed in the coelomocytes of the following strains (Ex signifies the transgenic array from which the indicated protein is expressed): a, +; Ex[MTM-6A::GFP]; b, +; Ex[MTM-6A(C335S):: GFP]; c,
mtm-9(
ar479); Ex[MTM-6A(C335S)::GFP]; d,
rme-1(
b1045); Ex[MTM-6A(C335S)::GFP]; e, +; Ex[MTM-6AdeltaFYVE::GFP]; f, +; Ex[MTM-6A (C335S)deltaFYVE::GFP]; g, +; Ex[MTM9::GFP]; and h, Ex[MTM-6A(C335S)]; Ex[MTM9::GFP]. Bar, 5 um in all images. (B) Coimmunoprecipitation of GFP-MTM-6A and Flg-MTM-9 expressed in human 293 cells. Antibodies against GFP or Flg were used to immunoprecipitate the corresponding fusion protein indicated above the gel. Blots were probed for the presence of the other fusion protein by using the antibodies indicated below the gel.
