Characterization of intestinal vesicles in lmd-2 mutants and LMD-2 protein. (A) Representative DIC and autofluorescence images shown in Fig. 1 A of intestinal cells of WT and mutant animals of indicated development stages. Arrowheads indicate intestinal vesicles with autofluorescence that were analyzed for diameters and shown in the right panel of Fig. 1 A. Scale bars, 5 μm. (B) Alignment of amino acid sequences of C. elegans LMD-2 and human LYSMD1 and LYSMD2. Identical amino acid residues are shaded in black. LysM domains are framed with red boxes.
