Fig. 3. fozi-1 encodes a novel protein. (A) fozi-1
gene structure (not drawn to scale) showing molecular lesions of
fozi-1 mutants. The first intron of fozi-1 spans 7 kb
upstream of the translation start site. (B) The structural motifs of
FOZI-1 include a Q-rich region (amino acids 88-133), two
C2H2 zinc finger motifs (amino acids 177-201) and an FH2
formin homology domain (amino acids 369-732). (C) pNMA04, pNMA27 and
pNMA28 are fozi-1 fusion constructs used to purify recombinant FOZI-1
fragments. pNMA36 and pNMA37 were used in transgenic assays.
